March 1942. Three months following the Pearl Harbor attack which thrust the United States into World War II, (and one month before the daring Doolittle Raid on Tokyo), the War Department ordered the commander of the Army First Corps General George S. Patton to locate, establish, and command a desert training area to prepare troops for desert warfare. Being a native southern Californian, General Patton did not have to look any further from his home in San Bernardino, CA, when he established the Desert Training Center at Shavers Summit (now known as Chiriaco Summit). It is here that my flight back in time is focused.

Go West Young Man

The lone airstrip (I wouldn’t even call it an airport!) designated as L77 on the far southeastern part of the Los Angeles Sectional Chart, is part of what is now the George Patton Memorial Museum. Our flight took place in the spring of 2003 from my home base airport Glendale Municipal Airport (GEU) in the western Phoenix metropolitan area, with two work colleagues looking for a real life history lesson.

Once departing GEU, you literally fly due west (adjacent and unique to GEU, is Luke AFB the home of the largest F-16 training facilities in the U.S. Air Force) while coordinating with the Luke RAPCON for safe passage and clearance to venture through their airspace. Once clear, however, it was literally IFR (I Follow Roads) flying because your route of flight is parallel to Interstate 10. An hour or so later you are arriving at L77, a one runway airstrip (6/24) and parking in the open ramp area south of the taxiway.

350 Miles Wide and 250 Miles Deep

It is here that our history story begins. The George Patton Memorial Museum is one of the hidden gems of military museums. It literally starts with the airstrip. In March 1942, General Patton and his staff established this southern California airstrip to not only allow air access for supplies and support personnel for his training center, but to also serve as a training platform for the Army Air Corp. (Over the years, such high-ranking Army generals such as Norman Schwarzkopf and Colin Powell flew in for special occasions.) Once inside the museum, there is a scale model diorama of the training center as it was during Patton’s time. To give perspective, the 350 miles wide and 250 miles deep location stretched from Pomona, CA to the east, Phoenix, AZ to the west, Yuma, AZ to the south and Boulder, NV to the north, an immense swath of land. But that was exactly what Patton wanted. Somewhere he could battle train his troops in the most realistic scenario that replicated the North African surroundings where they would soon be facing the German Commander “Desert Fox” General Rommel.

Exhibits throughout the museum are awe-inspiring. While museum staff has updated the motif and displays to highlight Desert Shield and Desert Storm circa 1991, and the most recent Iraq and Afghanistan wars, most of the exhibits pay tribute to General Patton’s history – from the famed pearl-handled revolvers, to his diaries, and the famous prayer he asked the chaplain to write during a cold European winter (as depicted in the 1970 movie Patton, starring Academy Award winning actor George C. Scott). Outside and surrounding the George Patton Memorial Museum grounds are former U.S. Army tanks and armored personnel from Patton’s era to present time.

Appreciation of the Past – Using Aviation As the Vessel

Now I know some of you may be thinking “That’s all well and good for the history buff, but aviation seems to be the backstory not the heart – like with your previous stories!” Ok, I admit it, this is a bit off the typical track you have been used to seeing from my stories, BUT, think about this for a minute: It was because of aviation that General Patton was able to sustain his men with supplies and additional personnel and equipment to create part of our “Greatest Generation” and it was with the ease of aviation that one can utilize in a quick, efficient (more fun) manner to explore little-known treasures such as this. There is a saying in the airport and aviation world that says: “A mile of road will get you one mile, whereas a mile of runway can get you the world!” All because of the wonderful world of aviation. Enjoy!

Are you tired? Maybe you need a nap.

Naps decrease the homeostatic drive for sleep by reducing the number of hours continuously awake, which results in a greater ability to focus. It’s like a reboot for your brain, shutting down the conscious processes of thought in favor of cellular recovery and the cleanup of waste chemicals. Studies indicate pilots afforded sleep during in-flight crew rest performed better on cognitive tests than those pilots who were only given a rest period where sleep was not permitted. But to most effectively combat aviation fatigue, when is the best time of day to take a nap? And how long should you nap to get the most benefit?

The best time of day to nap is during a Window of Circadian Low. The Window of Circadian Low refers to a specific time of day within the 24-hour circadian cycle in which subjects are primed for sleep. During times of circadian peak, the body’s physiological processes are programmed for an increased level of wakefulness. Conversely, during dips in the circadian cycle the body is gearing down for sleep.

Staying awake during a Window of Circadian Low can cause an increased level of fatigue because the pilot is working against the physiological processes which are preparing for sleep. Quite literally, you are fighting against your body to stay awake. Within the circadian cycle, researchers have identified two Windows of Circadian Low: at approximately 3am-5am and 3pm-5pm (Rosekind, Co, Gregory, and Miller, 2000). Many of us struggle through the afternoon hours yawning and drinking coffee, so if you get the opportunity, take advantage of the 3pm circadian siesta. Studies have also shown operations during a Window of Circadian Low can result in reductions in performance and alertness and increases in micro sleeps and errors (Rosekind, Gander, Connell, & Co, 2001; Caldwell et al., 2006).

The normal sleep cycle runs approximately 90 minutes and is comprised of sleep stages 1-4 and rapid-eye-movement (REM). Getting through an entire sleep cycle is a good idea, however, there are hazards to sleeping too long on your nap. Sleep inertia is defined by the Federal Aviation Administration as “… a period of impaired performance and reduced vigilance following awakening from the regular sleep episode or nap. This impairment may be severe, last from minutes to hours, and be accompanied by micro-sleep episodes” (FAA, 2010). Otherwise known as grogginess, sleep inertia can make waking up from your nap an undesirable experience as you try to get your bearings.

If you can’t get the full sleep cycle in, aim for less than 45 minutes, which reduces the occurrence of sleep inertia. By avoiding the deeper stages of sleep, you can also avoid the grogginess that comes with waking up in them. But remember, the best recovery happens in those final sleep stages and it’s important to spend as much time there as possible.

A Private Pilot Certificate doesn’t necessarily preclude earning money in aviation.

Vern Weiss

“No person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire, nor may that person, for compensation or hire, act as pilot in command of an aircraft.”

That’s what FAR §61.113 says and there’s no way to dance around it. By “compensation” we’re not just referring to money but, instead, anything of value.

This article should NOT be construed as legal advice. If you’ve got an idea to conduct operations (or validate them) as a private pilot certificate holder, the FAA and proper aviation legal counsel¹ should be sought.

However the FARs do allow a certain degree of accommodation so long as a private pilot is paid by his or her business or employer and the flight is only incidental to that business or employment and the aircraft does not carry passengers or property for compensation or hire.

Doctor Franklin owns a Beech Bonanza (as required of all doctors who are pilots). Ol’ Doc Franklin wants to attend the Annual Physicians’ Conference on Obscene Medical Fees in Atlanta. His partner, Doctor Taylor wants to go along. Both men are salaried and flying on company time. Is this legal pursuant to FAR 61.113? Of course it is. But let’s say Doctor Phillips wants to ride along and offers to pay Doc Franklin for flying him to the conference. Uh-uh. No-can-do! Doc Franklin can split the cost of the aircraft expense with the other two doctors but that is as far as it can go.

The Federal Aviation Regulations are quite explicit about what can and can’t be done with a private pilot certificate. One thing that a private pilot can do is give airplane rides for a charitable event or non-profit organization. However, there are some additional restrictions found in FAR 91.146 that must be met.

A private pilot may accept reimbursement of expenses involved in search-and-rescue operations under the auspices of a governmental body. Fortunately, search-and-rescue operations are not an everyday occurrence so let’s talk about careers in which you can fly as a pilot and receive pay.

Probably the most popular means of employment permitting you to fly and accept compensation is that of an aircraft salesperson. The regs prohibit you from such gainful employment until you have accumulated 200 hours. But after you’ve got 200 hours total time you can demonstrate an aircraft in flight to a prospective buyer while making money to do it.

Do you have a glider club nearby? Once you accrue 100 hours and meet the requirements of FAR §61.69 you can tow gliders or non-powered ultra light aircraft and receive compensation for your services.

Want to be a test pilot? According to the FARs, under FAR Part 21 a private pilot may act as pilot in command for purposes of production flight testing light-sport aircraft to be certificated in the light-sport category.

The definition of what constitutes a violation has ricocheted back and forth between the courts and the FAA for years. Remember earlier I said compensation is considered anything of value? According to the feds, this also means that a private pilot cannot barter pilot services for goods or services. “If you’ll fly me to Oshkosh this summer I’ll paint your garage…or give you my tickets to Saturday’s Cardinals-Phillies game…or…” Sorry. It’s all verboten.

Although it is not flying per se, a private pilot can use the certificate for many aviation-related careers and some of them are quite lucrative. Visit any of the Internet job boards and type “private pilot” into the search window. You’ll find good-paying jobs looking for people with a private pilot certificate in software development, avionics engineering and development, aviation product sales, airport management, FBO management and even in the “dark side” of aviation (as far as pilots are concerned these days) “flying” UAVs. The private pilot certificate is a highly sought after commodity and can link your other professional skills with positions that are allied to flying.

Other areas in which private pilots have tried to skirt the regs is by doing aerial photography and pipeline/power line patrol flying. Well-known aviation attorney and writer John Yodice² tells of one legal decision in which an attempt to nullify the restriction didn’t work. An employee of a power company proposed to his employer that he replace the company contractor used to fly patrols of its power lines. The rule of law is that the flying services must be incidental to the service being provided and the FAA said that since aerial power line patrol operations are a foreseeable and normal part of the power business, even if relatively infrequent, they are therefore not incidental. The power company must use commercially certificated pilots.

Careful of the “Smoking Gun”

Do private pilots fly for compensation and outside of the law? You bet. And some of them get away with it for a long time. There also have been local FBOs selling charters on their airplanes that do not hold Part 135 certificates and they merrily have got away with it; for a time. But run an airplane off a slick runway, clip a fuel truck with a wing or blow a tire on landing and the feds are going to put every aspect of your flight under their microscope. You don’t want it to surface that you received compensation for flying contrary to the FARs because it will become most unsavory for you. The FAA generally doesn’t fine pilots for violations. They go after certificate actions, which means suspensions or in extreme cases, revocation. More and more enforcement actions are blended into the Department of Justice these days so it isn’t worth making yourself vulnerable.

Keep your nose clean.

1 – I cannot stress strongly enough “proper aviation legal counsel.” There are attorneys running around out there who advertise in the Yellow Pages® that they are “aviation attorneys.” Was it Shakespeare that said, “A lawyer who holds a private pilot certificate does not an aviation attorney make?” Get recommendations and after talking to the attorney, if you are not dazzled by his or her aviation knowledge and expertise, run and don’t look back. I had to explain to one of those so-called “aviation attorneys” one time the difference between GMT/UTC and local time and that altitudes above 17,999 feet are called “flight levels.”

Declaring an in-flight emergency is not something to take lightly. Play this trump card if you need it but only if you need it.

Vern Weiss

What is an emergency? The FAA defines it as a “distress or urgency condition.” H-m-m-m…so would “I have to get home because the Super Bowl starts in ten minutes” qualify?” A sage old instructor once told me that some pilots make an emergency out of a mag check while others run out of fuel and merely request a lower altitude.

Is It a “Get Out of Jail” Card?

Let’s see if there’s any wiggle-room afforded pilots by the FAA regulations:

§ 91.3(b) In an in-flight emergency requiring immediate action, the pilot in command may deviate from any rule of this part to the extent required to meet that emergency.

§ 91.123(a) When an ATC clearance has been obtained, no pilot in command may deviate from that clearance unless an amended clearance is obtained, an emergency exists, or the deviation is in response to a traffic alert and collision avoidance system resolution advisory. However, except in Class A airspace, a pilot may cancel an IFR flight plan if the operation is being conducted in VFR weather conditions. When a pilot is uncertain of an ATC clearance, that pilot shall immediately request clarification from ATC.

(b) Except in an emergency, no person may operate an aircraft contrary to an ATC instruction in an area in which air traffic control is exercised.

…sounds pretty good on first glance. But let’s dig a little further…

The salient point made in FAR 91.3 is with the words “immediate action.” According to aviation attorney Gregory Reigel, “An emergency is a situation that could jeopardize the safety of a flight. The emergency situation cannot be of the PIC’s own making. That is, it must be unforeseen and unavoidable by the exercise of sound judgment. The PIC is responsible for making the determination as to whether an emergency exists and has the authority to take responsive action.” Attorney Reigel continues, “a PIC does not necessarily have to advise ATC of the existence of an emergency. Although in practice, declaring an emergency to ATC, if you are able, is a good idea since ATC will then give you the benefit of priority handling and additional assistance that may be needed to handle the emergency. that are reasonable under the circumstances.”¹

So we cannot infer from FAR 91.3 that boneheaded judgment is washed away by that permissive reg. In fact, depending on the extent of attention and disruption there probably WILL be an investigation and probably WILL be paperwork.

So when we declare an in-flight emergency, what happens? For one thing, WE might not even be the ones declaring an emergency! It can be declared for us. In addition to the pilot(s) an emergency can be declared by dispatch personnel, air traffic controllers, and company representatives. The latter may be done without the flight crew even knowing it. When an aircraft is in trouble, every resource becomes available to provide whatever assistance is needed to bring the aircraft safely back to Earth. This includes radar and DF facilities of both the ARTCC system and the US military and other governmental agencies such as the FCC and TSA.

After making such a declaration, the controller may prompt you to change your transponder to 7700. He may not do this and it’s up to you to switch over yourself.

Air traffic controllers begin routing all other aircraft so as to provide priority handling of the aircraft in distress. The controller’s handbook states that a controller is to “give the maximum amount of assistance judged to be necessary.” In addition, pilots can refuse or accept suggested or ATC instructed actions in the interest of safety. It is also incumbent on the pilots to communicate direness of a situation if they feel a controller is giving them an inappropriate command.

Important: Once an emergency is declared it can be withdrawn. Of course, whether the flight continues to land under an emergency declaration or not there will probably still be paperwork, depending on a lot of variables.

FAR § 91.3 (c) Each pilot in command who deviates from a rule under paragraph (b) of this section shall, upon the request of the Administrator, send a written report of that deviation to the Administrator.

Under Part 121:

FAR §121.557 (c) Whenever a pilot in command or dispatcher exercises emergency authority…The person declaring the emergency shall send a written report of any deviation through the certificate holder’s operations manager to the Administrator.

The in-flight emergency declaration is a tool to be used without fear of reprisal. The intent of the regulation is to ensure that a pilot will handle an emergency to whatever extent is necessary without fear of violation. One FAA inspector is quoted as saying, “I’ve never seen a pilot violated for deviating from a regulation when that pilot has either declared an emergency OR has stipulated in ANY written response to the FAA that an emergency existed at the time of the deviation.”²

In my career, I have declared an emergency on several occasions due to passengers experiencing medical problems. Even though it was in busy Class B airspace with a conga-line of other aircraft ahead of me on the approach, they all were held and we rocketed past them to the waiting ambulance on the ground and I’ve never been asked to submit any paperwork.

There are several tricks pilots use to circumvent declaring an in-flight emergency. Telling ATC you are “fuel critical” is not an emergency declaration. Advising the controller you’d “appreciate expediting the approach because we’re working on a problem” isn’t an emergency declaration. Declared emergency help is not provided unless a declaration is made and such should be the case only when it is possible or probable that there may be injury or loss of life. It is not used when you’re in a situation where you think you possibly could run low on fuel.

If you declare an emergency and must deviate from any regulation, just do it. You don’t have to tell ATC anything. Once an emergency is declared your radar symbol changes and AIRCRAFT EMERGENCY appears adjacent to your symbol on the controller’s screen. The controller will know you’re doing the best you can and you have free berth to use any judgment you feel is necessary.

I have heard pilots declare an emergency many times and the radio becomes eerily silent from that moment on. Other aircraft on the frequency are all listening intently to the unfolding drama. Once the distressed aircraft lands safely the controller often says something like, “Baron Six-Eight X-Ray, turn left at Charlie and contact ground. Good job.”

“Good job” are the words you want to hear after declaring an emergency and the pilot will often respond, “Back at-cha.”

Think you wouldn’t drink and fly a plane? You might be doing something similar without even realizing it. This article reveals the exact hour limit when your long day becomes intoxicating, and why you wouldn’t realize when it happens. Understanding your limits, and how they’re affected by stress and fatigue in aviation is knowledge that will make you a better pilot, and may even save your life.

Scientists currently believe that stress and fatigue in aviation are developed from a variety of sources, and no one is immune from them. Although the effects on the body are different, excessive exposure to mental stimulation produces the same measurable results as extensive manual labor and leads to a decrease in the ability to carry out tasks. (FAA Publication, Medical Facts for Pilots, 2002). Any person operating in a fatigued condition, regardless of the cause of fatigue, will exhibit the same problems.

Historically, research indicates obtaining adequate sleep is the best way to prevent or resolve stress and fatigue in aviation. However, because of the complex nature of the body’s response to a variety of factors other than sleep deprivation, adequate sleep is not to be considered a complete solution in fatigue management. Because of the dynamic environments in which we operate, our body’s experience a myriad of situations and events which lead to the effects of fatigue. Sleep deprivation directly contributes to fatigue because the body does the majority of its recovery during sleep.

Sleep Deprivation

Sleep deprivation refers to no sleep or a reduction in the usual total sleep time. Various amounts of sleep deprivation have shown to reduce cognitive function and can negatively impact performance levels. Sleep deprivation affects the performance of sustained attention tasks and manifested itself in a higher number of omission errors (Fafrowicz et al., 2010). These omission errors, defined as “lapsing or failing to respond in a timely fashion to a presented stimulus”, are related to micro sleeps and increase under high fatigue conditions (p.940).

Durmer and Dinges (2005) conducted several partial sleep deprivation studies, which indicate a suboptimal sleep dose has measurable effects on concentration and the performance of cognitive tasks. Reports have shown that the average sleep obtained by a pilot is approximately 6 hours per night. Over a two-week span, the body’s response to sleeping only 6 hours per night is similar in cognitive ability to operating under an entire night of sleep loss. Think about this for a moment…let it sink in…the average pilot is operating on a day-to-day basis, flying their aircraft with the same cognitive ability as if they’ve just been awake all night.

For those individuals receiving only 4 hours of sleep during the same span, the cognitive effects are comparable to an entire weekend of sleep loss (Durmer and Dinges, 2005). Hopefully, you are all getting more than 4 hours a night. While no cognitive deficits occurred for 8 hours of sleep per night, 1 hour of sleep loss per night causes reduced waking alertness, and 2 hours of sleep loss can “significantly affect both alertness and performance” (Rosekind, Co, Gregory, and Miller, 2000, p,4). These studies have shown there is a consistent decline in cognitive ability due to sleep loss and denote the importance of attaining the recommended 8 hours of sleep per night.

It is also known that subjective reports of fatigue are typically underestimated, as individuals “are often sleepier than they report” (Overton and Frazer, 2013, p.219). Studies using physiological measures of sleepiness have shown that people can, “report a high level of alertness during the day and yet still exhibit significant physiological sleepiness” (Neri, Dinges, and Rosekind, 1997, p.11). This alludes to the role of environmental stimulation in the individual perception of stress and fatigue in aviation and identifies a cognitive disassociation between how the subject feels and their actual physiological state. This disassociation inhibits the pilot from realizing when they are fatigued, thereby making it impossible to accurately report their fatigue level. If you ask the pilot, they will feel rested enough to fly, even if they are not. Without as much environmental stimulation, such as in the early hours of the morning, their actual level of physiological sleepiness may make it impossible to stay awake.

Kuo et al. (1998) found that “during chronic partial sleep deprivation, subjective sleepiness increased during the first week, but decreased during the second week, suggesting that subjects believed they were adapting to the effects of sleep loss, whereas performance measures indicated that they were not: (Kloss, Szuba, and Dinges, 2012, p.1900). Because of this illusion of adaptation to the effects of chronic partial sleep deprivation, pilots may believe they are fit for duty when in fact they are experiencing a dangerous level of fatigue. While most pilots are not subject to periods of acute total sleep deprivation, chronic partial sleep deprivation is a highly common occurrence in the aviation operational environment. Because of the effects of fatigue on perception, when “attempting to judge how sleepy an individual is, the worst person to ask is that individual” (Neri, Dinges, and Rosekind, 1997, p.11).

Cumulative Sleep Loss

Another factor which must be considered is cumulative sleep loss, or sleep debt. Sleep debt is the accumulation of missed sleep over several days or weeks, which an individual has not had the opportunity to make up. Any sleep of less than 8 hours per night may result in a sleep debt. If you miss three hours of sleep on Wednesday, and one hour of sleep on Thursday, by Friday you are operating under 4 hours of missed sleep. According to one study, it takes more than the recommended 8 hours of sleep to make up a sleep debt, as sleeping 8 hours merely fulfills the daily requirement for sleep, thus “two nights of recovery sleep are typically needed to resume baseline levels of sleep structure and waking performance and alertness” (The Royal Aeronautical Society, n.d.).

Cumulative sleep loss can be any combination of total or partial sleep loss, and cognitive effects have been shown in as little as 1 hour of missed sleep per night. Studies have shown that “4 or more days of partial sleep restriction involving less than 7 hours sleep per night resulted in cumulative adverse effects on neurobehavioral functions” (Durmer and Dinges, 2005, p.123). Along with the increase in sleep debt, there is also an increase in attention lapses and daytime sleep propensity, and a decrease in cognitive speed and accuracy on working memory tasks (Van Dongen, Maislin, Mullington, & Dinges, 2003; Drake et al., 2001; Dinges et al., 1997; Belenky et al., 2003).

Hours of Continuous Wakefulness

Hours of Continuous Wakefulness refers to the number of hours since the last sleep episode. Durmer and Dinges (2005) suggested that there is a critical period of stable wake time within each circadian cycle, after which neurocognitive deficits occur. They have statistically estimated the optimal sleep time to be 8.16 hours, with the corresponding 15.84 hours of wakefulness completing the 24-hour circadian cycle (Durmer and Dinges, 2005).

According to current research, there is a drive for sleep which increases progressively with the duration of time the individual spends awake. In a study comparing the cognitive effects of this homeostatic sleep drive and the cognitive effects of alcohol, The Royal Aeronautical Society found, “after 17 hours of continuous wakefulness, cognitive psychomotor performance decreased to a level equivalent to a blood alcohol concentration of 0.05%”, and “after 24 hours of continuous wakefulness performance was approximately equal to a blood alcohol concentration of 0.10%” (n.d.). Additionally, NTSB investigations have found that flight crews on long duty days (a shift of more than 13 hours) exhibit a disproportionate amount of accidents when compared to those on short duty days (a shift of less than 13 hours) (Federal Aviation Administration, 2010).

The legal limit of alcohol intoxication to operate a vehicle in most States is 0.08%. To put it into perspective, if you have been awake for 17 hours, your brain responds as if you were over halfway drunk by vehicle standards, and over the limit to fly an aircraft. The federal blood alcohol limit for pilots is 0.04%. Should you be flying 17 hours after waking up? Absolutely not. This poses a problem for pilots working evening shifts, as they probably woke up early in the day, and were awake all day, and then started their shift, putting them in a situation where they are operating under the influence of fatigue. The FAA has taken a hard line against alcohol, adhering to the strict limit of 0.04%. Out of the thousands of pilots tested each year, only a few of them fail the breathalyzer, and alcohol-related crashes are rare. Since pilots cannot come to work drunk, it makes sense to limit their operational usefulness if they are known to have been awake for a duration in which intoxicating effects are present, regardless of the cause. Schedulers should also be aware of this limitation caused by stress and fatigue in aviation, and not assign pilots more flights than safety permits, based on the duration of time they’ve been awake.

Airline careers necessitate long hours of crushing boredom punctuated by short periods of intensity. The unique demands placed on airline pilots, crewmembers and mechanics can be met with lifestyle and attitude adjustments.

Noah Timmins

Aviation distinguishes itself from other industries as one that eschews the traditional “nine to five”, “clock in, clock out” work schedule. The unique nature of air travel refuses to play nice with normal concepts of schedules, routines, or habits. In order to accept a career with the airlines, one must have an understanding of the real demands of airline careers.

The penultimate goal of aviation is to ferry passengers and cargo from one location to another in a manner both safe and efficient. Achieving this goal takes superhuman effort from a broad range of people involved in the successful launch of an aircraft. Let us take a snapshot of the demands placed upon people in three rungs of the aviation ladder: maintenance, dispatch, and carriage.

Airline Careers For Mechanics

Airline mechanics must keep aircraft safe for flight. Strict regulations require extensive documentation and procedure control, lengthening the time mechanics must spend on each maintenance operation. Unfortunately, an aircraft grounded due to maintenance earns no money, requiring mechanics to work quickly. These two aspects come together forcefully, causing mechanics to work long hours, under stress from airline owners. Additionally, mechanics have no room to make mistakes, as one mistake in maintenance can quickly snowball into the loss of hundreds of lives.

One small omission of a sheet metal repair once caused the death of 520 souls. When Japan Airlines Flight 123 encountered a tail strike incident in 1977, the damage was repaired by installing a new piece of metal over the affected area and the plane was declared airworthy. In 1984, that same section of the tail cone underwent explosive decompression, destroying a piece of the tail, and sending the aircraft into an uncontrollable state. It crashed into the ground, killing 520 people of the 524 on board. This is the deadliest single-aircraft accident in aviation history and the second deadliest behind the Tenerife disaster.

The root cause was a single small step being omitted in the repair process. One person missed one thing, and 520 people died. This kind of stress is placed on mechanics daily: extensive paperwork documentation required by the FAA attempts to counter these incidents. At the end of the day, however, mechanics must maintain strict vigilance, operating one-hundred percent perfectly under the stress of timetables. Joining an aviation career as a mechanic is a daunting step and not to be taken lightly.

Airline Careers For Dispatchers

Aircraft must not just be airworthy, but also, be flight ready. This falls under the authority of aircraft dispatchers. In terms of airline careers, dispatchers are responsible for organizing and planning flights for an airline. They must keep track of thousands of different things: aircraft maintenance status, patterns of weather, availability of food and fuel, assignment of personnel, and management of aircraft flight times. These people form the backbone of organization for an airline, keeping planes on schedule and ensuring that the carriage of people and cargo is both safe and efficient.

Dispatchers also suffer from the pressure of financial accountability: they solely are responsible for aircraft arriving and departing from airports at specific times, thus, they control the revenue stream for airlines on the ground. Without dispatchers, no airlines would able to maintain a set schedule with fully stocked aircraft and up-to-date maintenance.

Offices for flight dispatchers are hectic environments. American Airlines employs over 1,600 dispatchers at their Forth Worth control center, all working in the same huge room. People scurry about, constantly busy, ensuring that all the stars align for successful aircraft launches. Tickers and charts dot the walls, like a scene from the New York Stock Exchange.

Like the exchange, things can change at the drop of a hat. A plane might suddenly develop a maintenance issue, or an airline servicing cart might be running late. Dispatchers must be able to find a way to solve this problem, without even having minutes to spare: customers will often be sitting in the plane, on the tarmac, impatiently waiting for takeoff. Their enjoyment of the entire process – and thus their opinion of the airline – could change right at this moment. Dispatchers do not have the luxury of time on their side, thus, they must develop a sense of urgency in their job.

However, dispatchers must also not make mistakes. Like the mechanics, a simple error can lead to a major catastrophe. UPS Flight 1354 into Birmingham, Alabama, flew into the ground in 2013, impacting terrain short of the runway, destroying the airplane. The plane was perfectly airworthy, the pilots were fit for duty, and there was no inclement weather. The issue? Dispatchers sent the airplane to the airport for an instrument flight rules landing, even though the instrument landing system at the airport was inoperative. Effectively, this required the pilots to hand-fly the airplane in for a landing, something they had not planned for due to the mistake made way back at the dispatcher’s office.

This little break in the normal chain of an aircraft landing was enough to push the pilots outside of their comfort and ability zone, causing a further breakdown of situational control, and ultimately leading to the loss of both pilots’ lives and the airframe. All this due to the simple error of one person missing a line in the airport status information panel halfway across the country. The slightest little mistake could quickly snowball out of control, bringing down an airplane and – worse – its load of passengers. This is one of the hardest adjustments to make when pursuing a career in aviation: adopting the mindset required to take the grave responsibility of ferrying people through the air.

Airline Careers for Pilots

Lastly, the pilots. Pilots are the ultimate end-all be-all of safe flight. They are the ones in command of the aircraft from when the wheels leave the tarmac until the inevitable return to ground. Pilots form the “last line” of defense against human mistakes and mechanical errors. This puts them in the most important position of an airline, in terms of having the ultimate responsibility for the safe carriage of passengers. Airline careers as a pilot are a solemn undertaking not for the faint hearted.

Everything a pilot does is regimented to the final letter. Every procedure has a physical checklist called out for it, describing the process required and spelling out each step individually. The presence of both a captain and a first officer ensures that a “call and response” style of completing checklists is accomplished on the flight deck. The first officer will call a requirement, such as “Flaps to fifteen degrees”, to which the captain will comply with, then respond with “Flaps, fifteen”. This process ensures that each checklist operation is completed without any possible errors, and has proven its track record: flying through the air is the safest form of travel today.

This small glimpse into the pilots’ routine in the cockpit highlights the importance of each decision the pilot makes. Moving the incorrect switch in the cockpit could put a plane into a situation that requires an emergency landing or becomes unrecoverable. The famous Air France Flight 447 accident over the Atlantic Ocean in 2009 puts this in perspective: the airspeed indication devices of the aircraft became filled with debris, giving the pilots no indication of the speed of the aircraft. This caused the autopilot – responsible for maintaining level flight – to disengage, causing the aircraft to roll right. The pilot, noticing this, grabbed the control stick and wrenched it left in an effort to bring the aircraft level. However, this control input was actually an over-control input, which dragged the aircraft too far into a left roll, causing an aerodynamic stall and the subsequent loss of life and the airframe.

Effectively, the pilot panicked.

This quality is exactly why airlines put such a strict regulation into flight deck management. Pilot training is a 3,000 hour ordeal of managing the flight deck of an airplane. A large portion of this is spent learning how to make decisions. With the control stick in the left hand, the throttle in the right, and 100 souls on board, a pilot’s decision in flight is something that is not taken lightly.

Learning how to fly a plane is a deceptively simple task. Any person can consistently hit the 1000-foot marker on the runway during an instrument landing in a deadly crosswind. All that requires is skill, and skill can be learned. Spending 3,000 hours flying commercial aircraft will give a pilot that skill. The difficult part about piloting is the part that can only be learned and cannot be taught: being a decisive person. The decisions made on the flight deck of an aircraft are the penultimate example of swift thought and swift action.

Captain Sully’s actions during the famous Miracle on the Hudson are a prime example of the character demanded of pilots. US Airways flight 1549 impacted a fleet of birds shortly after takeoff from LaGuardia airport. Both engines of the aircraft immediately lost power. The first officer grabbed the emergency checklist for engine restart – the proper decision – while Captain Sully immediately grabbed the controls, ready to input commands. Unfortunately, due to the nature of the New York City layout, a suitable diversion was unavailable, due to the low altitude of the aircraft. Realizing this, Sully announced to the air traffic controllers that he would attempt to land on the Hudson river. Landing an aircraft successfully on water was considered practically impossible, making Captain Sully’s decision seem poor.

However, Sully had made his decision. He could have attempted to divert to a possible airport, or attempted to land on a highway, but he had already laid his cards on the table. All of this decision-making occurred over a period less than two minutes. Sully’s approach to the river was cleverly placed: he avoided the cross-river bridges and brought the aircraft down near ferry terminals. The aircraft impacted the water with the aft fuselage – not the engines – resulting in a hard but safe landing. Recovery was successful, with no loss of lives. The NTSB praised Sully, calling it the most successful ditching in airline history.

Captain Sully had a remarkable level of skill at piloting aircraft, being professionally glider trained. More importantly, however, he displayed exceptional decision-making ability. Several alternatives presented themselves. He could not turn around to LaGuardia, he was too slow to make the turn. He could not continue on to New Jersey, he was too low in the sky. He could not land on the highway, it was too far away. His only option was the river, but it was a bad option. Nonetheless, his decisive action brought him to follow-through with his less than optimal decision, saving the lives of hundreds of people.

In Conclusion

Incidents like that highlight the necessity of decision making. This alone will be the hardest step in accepting airline careers. Mechanics, dispatchers, and pilots all face decisions daily that could have disastrous results if performed poorly. However, strict training and attention to detail, combined with the proper attitude of responsibility, will ensure that people depart and arrive safe and on time. This attitude takes time to develop and comes with experience. In the end, the feelings of successfully delivering people is well worth the effort.

Upper Limit Aviation’s recent open house was featured on KUTV News, as one of their featured STEM stories.¹ Upper Limit staff headed into the 2News studio to show off some aviation related tools and discuss what would be covered at the aviation open house.

ULA started by showing sectional charts, flight plans, and an iPad, and discussing the recent advances in aviation technology aimed at making navigation more streamlined for pilots.

“We’ve really progressed a lot from the paper and pencil charts, and technology has come forward leaps and bounds, and now we’re using iPads, we’re using computers … before you’d have to carry five or six paper charts just to make a flight, now you can just move around the country simply by the scroll of a finger.”

Also discussed in the video were the importance of the weight and balance and center of gravity calculations for an airplane and how they affect flying, and some more details on the upcoming aviation open house.

“We’ll have pathways to careers, from piloting to air traffic control, and all aspects of aviation.”

The open house, which took place on Saturday, April 30^th, at Upper Limit’s Salt Lake campus, featured access to aviation professionals such as pilots (including commercial airline pilots), mechanics, air traffic controllers, airport operations personnel, flight attendants, military veterans, FAA representatives, and aerospace engineers. A large number of aviation-related businesses and organizations had representatives in attendance as well, including Boeing, Delta Airlines, and the US Air Force.

The aviation open house was a success, with crowds of people in attendance, and Upper Limit hopes to host another one soon.

In order to achieve a viable solution for fatigue in pilots, we must consider the current beliefs, opinions, and assumptions in the science of fatigue and fatigue management. There is a general consensus in the scientific community about what causes fatigue, and much research has been accomplished in studying the body’s response to operation in the realm of fatigue. Several factors have been proven to contribute to an individual’s level of fatigue, including diet, level of physical activity, circadian disruption, the presence sleeping disorders and exposure to sustained stress. Since there are several factors which contribute to fatigue in pilots, each of these factors must be addressed and an appropriate solution achieved.

The situations and pressures that cause stress are known as stressors. We usually think of stressors as being negative, such as a taxing work schedule or poor relationship. However, anything that puts a high demand on you or forces you to adjust can be stressful. This includes positive events such as getting married, buying a house, or simply receiving a promotion. Prolonged stress has certain degrading effects on the body, which includes cognitive symptoms, such as the inability to concentrate; emotional symptoms, such as feeling overwhelmed; physical symptoms such as nausea and dizziness; and behavioral symptoms such as the inability to sleep.

Each individual’s tolerance for stress is unique. Some people can handle more stress than others due to their individual experiences and psychological makeup. According to an article by Dr. John Anne titled Stress Reduction – Which Techniques Can Be Used to Reduce Stress, stress creates a physical condition that increases the occurrence of various health problems:

“Chronic stress may lead to unpleasant conditions even for the strongest individuals. Prolonged stress can cause a permanent biochemical imbalance in the health system. This eventually leads to a weakened immune system and increased vulnerability for serious health conditions, which may be proven fatal in due course of time. Stress is known to develop various health complications such as asthma, cardiac complication, high blood pressure, allergy, fatigue, depression, insomnia, anxiety, irregular bladder, headaches, body pain and many more. (2007).”

If you do not manage long-term stress effectively, it can lead to long-term fatigue, failure, or one of the many forms of physical or mental ill health.

It is known that pilots experience high levels of stress due to the sustained attention and decision-making capability required to fly an aircraft. Gregory, et.al have shown that during the descent phase of flight, the pilot controlling the aircraft experiences an increased heart rate, signifying an increased level of stress. (1994). When under the effects of stress, the body responds by emitting cortisol from the adrenal glands located on the upper side of the kidneys. Cortisol is produced to assist the body’s natural response to stress, the need to fight or flee the situation. In an aviation environment, there is no one to fight, and nowhere to flee, so this cortisol is not used appropriately. With no outlet, the cortisol remains in the system in high levels for an extended period of time, doing damage to the cells of the brain and body, and resulting in sustained levels of anxiety and reduced cognitive ability.

One reliable way to reduce cortisol levels in the body is massage. According to a study conducted by the University of Miami School of Medicine, “cortisol levels decrease dramatically post massage, and have been reported decreasing by as much as 37% over recorded pre-massage levels.” (2005). Massage also increases the level of dopamine, a brain chemical which is responsible for keeping the brain alert and awake, and serotonin, which works against cortisol, producing a calm and relaxed state. (University of Miami School of Medicine, 2005).

Studies have shown that massage will decrease the effects of stress and fatigue on the body by speeding the elimination of chemical waste produced by the body, in both animals and humans. This information has been around for quite some time, as J.H. Kellogg, M.D. wrote in The Art of Massage about the ability to remove the effects of fatigue by administering massage:

“In cases of exhaustion from excessive mental, nervous, or muscular work, general massage secures the most marked and satisfactory results, relieving the sense of fatigue in a most wonderful manner, and in cases of muscular exhaustion, restoring muscular power in a remarkably short space of time. Ranke, Helmholtz, Du Bois-Raymond, and more recently, Abelous, have conclusively shown that special toxic substances are produced as the result of muscle work, and that the phenomena of fatigue are due to the influence of these substances upon the nervous and muscular systems. Zabloudowski has shown that frogs completely exhausted by faradization of the muscles, although not restored by fifteen minutes’ rest, were revived at once by massage, and were even able to do twice as much work as before. In another experiment, a man lifted with his little finger, one kilo (2 1-5 lbs.) 840 times, lifting the weight once a second. The muscles of his finger were then completely exhausted. After five minutes’ massage he was able to lift the same weight 1100 times, and his muscles were even then not greatly fatigued. Mental fatigue is also relieved by massage, through its effect upon the circulation and the eliminative organs. The toxic substances produced by mental activity, are more rapidly oxidized and removed from the body, while the hastened blood current more thoroughly repairs and cleanses the wearied nerve tissues. The entire nervous stem, through the improved nutrition induced by massage, experiences general reconstructive effects. (1895).”

A certified massage therapist, Vicki Platt, highlighted recent findings on the effects of massage in the workplace, including a five-week study at Bowling Green State University, proving massage has the ability to increase mental alertness:

“The individuals who participated in the study were massaged twice a week and completed a math test in half the time, with half the errors as the control group. (2007).”

The investigations listed herein have shown that massage is one of the most effective ways of influencing the human body’s ability to eliminate toxic substances, and thereby recover from both mental and physical fatigue. Massage has the ability to speed the recovery from fatigue at several times the rate of rest alone, and revive the muscles to potentially do more work than they previously could. As massage speeds the removal of the chemicals that build up in the brain, the way is cleared for the continued chemical processes of decision making and sustained attention required for flight. As the waste products are removed, mental clarity is restored and faster response times become possible. Massage results in faster recovery from fatigue in pilots and resets the body’s ability to handle the next dose of stress and fatigue aviation schedules deliver. This information is not new, but it has not been applied to the aviation industry as a legitimate finding on fatigue, and as of now there are no programs available that incorporate these principles.

A massage program, when applied to the aviation industry, has the potential to reduce fatigue in pilots and thereby increase safety, and should be incorporated for those positions which normally experience high levels of stress. While it’s not practical or cost effective to provide each pilot with a personal post-flight massage, obtaining a massage chair for regular home use, and a couple of massage chairs in each pilot’s lounge is highly recommended to relieve the effects of fatigue in pilots, promote better sleep, and keep cortisol levels to a minimum. A program to finance massage chairs during flight training would put the solution for the problem of fatigue in pilots where it’s needed the most, and has the potential to reduce training times due to the increased ability to focus and process information. An airline safety program element to provide massage chairs for post-flight use in pilot lounges would increase safety and reduce overall healthcare costs for the airline. As we hold consistently high standards for our pilots, we can also give them the tools to be successful in delivering consistently excellent results. Massage is the missing link in the fight against fatigue in pilots. Although it seems like a luxury item to many, science has proven it to be a necessity for the sustained 24-hour operations and attentional requirements of our top performers, the pilots.

Think you wouldn’t drink and fly a plane? You might be doing something similar without even knowing it. As our journey to cognitive excellence continues, we’ll see the scientific comparison between being awake and being drunk in Unsolved Issues: Part IV, Stress and Fatigue in Aviation: Looking at Continuous Wakefulness and Sleep

Don’t forget to take the Dramamine before you fly… not after.

Shawn Arena

This article highlights the importance of a dialogue with your first time and even seasoned passengers before flying, a sort of pre-flight discussion. You should be prepared to inform them of all aspects of the upcoming flight, and don’t forget to ask them about any concerns or comments they may have prior to the flight as well, if not an unexpected surprise may pop up…as I found out during this experience!

All In the Name of Charity

In April 2000, my wife organized, coordinated, and supervised a charitable silent auction held at our special-needs eldest son Matthew’s school in the northwest Phoenix area. Titled “Miles of Smiles” this event was in its second year after a successful inaugural launch in 1999. Among all the neat and exciting things donated by local Phoenix businesses and sports teams (the Arizona Diamondbacks and Phoenix Suns), my wife had arranged with me to fly one lucky parent and their special needs child to Sedona Airport (SEZ) in northern Arizona for breakfast.

The lucky father Pete and his son Max were the winners for this adventure. After some coordination during the following week, Pete and I decided that May 6th would be the appropriate day. Now I must caution (or more likely advise) anyone who wishes to conduct a charity flight such as this to contact your local Flight Standards District Office (FSDO) for proper authorization to conduct such flights. After proper coordination with the PRC FSDO, we were good to go. Additionally, when a pilot wishes to venture into the world of special needs individuals, focused attention on the individual (and caregiver) must be heeded because this more than likely will be something so foreign to them, you do not want any unintended consequences to occur that would endanger all occupants in the plane

Well at Least the Flight to Sedona Was Uneventful

Springtime in Arizona is a wonderful time to fly. It is the ‘hot’ time of year and has not yet reached the ‘hotter’ time, and weather conditions are very favorable. However, it must be noted, that it can be warm enough even in the morning hours, to prompt an early departure ahead of the warm-up of the day.

Departure from Glendale Airport (GEU), was uneventful, and our Cessna 172S (N234SP) purred like a kitten as we climbed and comfortably cruised at altitude. SEZ sits on a mountain mesa at 4,817 ft. MSL among one of the most picturesque areas in the world – Red Rock country. Max thoroughly enjoyed the flight, Pete while a bit apprehensive, also seemed to settle in nicely. My youngest son Andrew also came along for the ride. We landed on runway 03, taxied to the transient tiedown area, and were looking forward to a delicious breakfast.

You Should Have Said Something To Me Earlier

After breakfast, it was back into the plane and ‘literally downhill’ back to the Phoenix metro area. Just a few minutes into the flight, I thought I heard a noise from the back seat area and asked Andrew to look back to see what it could be… ”Max’s dad is throwing up Dad” was Andrew’s reply. Uh, oh I thought to myself, we better go to hyper speed to get home ASAP. “It’s OK dad, he’s upchucking in the diaper bag,” Andrew so eloquently informed me.

Now I am about to share something personal, and I don’t introduce myself as this, but I am a sympathetic puker! I thought “Oh, boy Shawn, just focus on listening to ATC and concentrate on flying the plane and getting back to GEU.” I instinctively told Andrew to turn all the air vents on his face and take deep breaths into them, as I did the same. The remaining hour of flight was tolerable, though I was concerned about how much of the backseat I had to clean up when we got home.

We touched down back at GEU and taxied (in my best Southwest Airlines brisk style) as I could and opened the doors and windows to help the air quality. To my amazement, there was not a drop in the back seat, for Pete (smartly) tied up the diaper bag to prevent any ‘air leakage.’

Walking back to the FBO office to turn in the keys I asked Pete if he was OK. Sheepishly and embarrassed, he said yes and then this pearl of wisdom came from his mouth…” I guess I should have taken the Dramamine before we left, instead of after breakfast.”

“What?“ I thought to myself as I figuratively wanted to choke the guy (but held back just in case any ‘residuals’ might come out). So calmly I told him, “Yes you should have AND you should have informed me you needed to take it before we left.”

Another Lesson Learned, This Time About Pre-Flight

So while “Pete’s adventure” was the lowlight of the flight, I too learned a valuable lesson. Remember that important pre-flight discussion I mentioned at the beginning of this article?

As part of my pre-flight routine, I now ask all passengers if they are prone to motion sickness BEFORE we get to the airport, so we can stop for counter-acting medication on the way. When I earned my Private Pilot Certificate, the FAA Examiner flippantly told me…” Now you have your license to learn.” Boy, how true that statement remains. Happy Flying!

A communications failure can be a scary thing – even on a beautiful VFR day. But throw in some clouds, limited visibility, and mountainous terrain, and suddenly this can be absolutely terrifying! As a pilot, maintaining a cool head and knowing your procedures will ensure this situation doesn’t get any worse.

Scenario

ATC has cleared you to RYANN via radar vectors as filed on your flight plan. Your last assigned altitude was 8,000 feet. On the way to RYANN, you determine that your radio will neither transmit nor receive. You are in visual meteorological conditions (VMC). Panicked? What do you do?

If you’re VMC, it’s actually not that complicated. Set your transponder to 7600 and proceed VFR, landing as soon as practicable. But what if you have your instrument rating, and you’re in instrument meteorological conditions (IMC)? You can’t just descend down through the clouds on your own, so what do you do now?

There are three major things to take into consideration after setting your transponder to 7600. The three things you need to determine are you routing, altitude, and clearance limit.

Routing

Take a stroll down Avenue F. This is your mnemonic device – AVE F. Your routing priorities are, in order:

Assigned – your last assigned clearance by ATC

Vectored – your last assigned vector by ATC

Expected – your last expected clearance given by ATC

Filed – your IFR flight plan as filed with ATC

So, if you received radar vectors to a fix where you would then pick up the rest of your IFR flight plan, you proceed on that vector to that point and then pick up your routing as filed. In the case of this scenario, you would continue to RYANN and then to your next point as filed.

Altitude

What’s that important altitude between fixes on IFR charts? The minimum enroute altitude, or MEA? This is your next mnemonic device – MEA. Your minimum altitude to maintain is the highest of:

Minimum enroute altitude – the MEA listed on the chart

Expected altitude – the altitude ATC said for you to expect in a further clearance

Assigned – the altitude last assigned by ATC in your last clearance

So in our scenario, ATC last assigned an altitude of 8,000 feet. But looking at our IFR chart we see that the MEA for our routing (if we were flying northwest) is actually 10,000 feet. We must fly the higher of these, so we’d have to initiate a climb to 10,000 feet.

Clearance Limit

You’re going to have to continue the flight and eventually land. So where and when are you going to do this? We need to figure out our clearance limit. Fortunately, our IFR flight plan has a final fix and an ETA to help us with this.

First, we need to know if ATC gave us an expected further clearance. This is something we receive if we’re holding due to ATC or other delays. If we’re holding at an Initial Approach Fix (IAF) then we commence our approach once we get to the time ATC gave us in the EFC. If we’re not at an IAF, then we leave our holding fix at the EFC, proceed to the IAF, and hold as necessary to commence the approach as close to our ETA as possible.

If we don’t have an EFC, proceed to an IAF if not there already and start the approach as close as possible to our ETA.

• We have an EFC
  • Fix is an IAF: Commence approach at EFC
  • Fix is NOT an IAF: Proceed to an IAF at EFC and commence the approach at ETA
• We don’t have an EFC
  • Fix is an IAF: Commence approach at ETA
  • Fix is NOT an IAF: Proceed to an IAF and commence the approach at ETA

In Conclusion

Enroute communications failures on an IFR flight plan isn’t as scary as it may seem as long as we know what to do. Just remember the three major ingredients we need to safely carry out our flight plan.

Routing

Altitude

Clearance Limit

We go down AVE F for our routing, fly the MEA for our altitude, and go to an IAF for the approach at either our EFC or ETA. It’s really as simple as that.

Shawn Arena

Welcome back! This is another installment of my personal flying experiences that hopefully others can learn from as well. The twist to this true tale, however, originates from a former student of mine who reminded me of the pitfalls and potential dangers of density altitude operations.

The Prelude

September 20, 2000, was a typical end of summer day throughout Arizona. The annual monsoon season was coming to a close, so the temperatures throughout most of the state were starting to ‘dip’ below 110 degrees. On that Wednesday afternoon, I flew three Arizona airport manager colleagues to a quarterly manager’s meeting to Flagstaff (FLG) from my rented aircraft’s home in Glendale, AZ (GEU).

While I was the airport manager at Phoenix-Goodyear Airport (GYR), I also was an adjunct assistant professor at a nearby college flight program. At the time of the flight, I was instructing an undergraduate Airport Management course, and one of my students (Herman) was also a pilot. One day after class, while he and I were chatting about the course, I mentioned to him that I had scheduled an upcoming flight with three other airport managers to Flagstaff (which for me was to be my first flight to FLG). It was then (as I thoroughly understood after the fact), that I was to learn my first lesson in Density Altitude operations.

A Good Lesson Plan

About two weeks prior to that flight, I was checked out in the flight school’s Beechcraft Sierra (Be-24), because I dreamed of (and still do) getting checked out in a Beechcraft Bonanza (what is referred to as the Cadillac of single-engine aircraft) one day. Since the school did not have a Bonanza, I thought the Sierra would be a good stepping stone towards it. This upcoming flight was to be only my third flight in the aircraft. In our impromptu meeting, Herman reminded me several times “don’t top off the fuel tanks at FLG because density altitude may bite you.” For those unfamiliar with density altitude and its dangers, let me conduct a quick Weather Flying tutorial for you.

Density altitude is pressure altitude corrected for nonstandard temperature. As temperature and altitude increase, the air density decreases. For a pilot that can be a recipe for trouble if he or she is not aware of the conditions. Since the air at higher altitude is less dense, it takes a longer takeoff roll on the runway, and the climb to altitude is slower.

Flagstaff-Pulliam Airport (FLG) sits at the 7,000-foot elevation level in northern Arizona and runway 3-21 is 8,800 feet long. On the day of the flight, the outside temperature was a ‘cooler’ 85 degrees. There you have it: high altitude, high temperature, and lower aircraft performance.

OK Baby, Just Keep on Climbing

The incoming flight was uneventful (oh, I must add, at GEU the departure airport, at 0900 local time it was 95 degrees), so the coolness of FLG would be welcoming. Our departure was at 1:00 PM local time immediately following a delicious catered lunch. Unaware to me until I started my takeoff roll, the entire group of managers watched our departure from the balcony of the airport terminal (oh great, no pressure here Shawn).

I vividly remember lifting off at the 3000-foot remaining point and then it hit me – Herman was right, our aircraft sluggishly lifted off and barely started a climb at the rate of 100 feet/minute. Lesson learned, density altitude is nothing to mess with! Interstate 17 runs adjacent to the airport and heads due south. I made a slight course correction to fly IFR (I Follow Roads) and wanted to stay within landing distant of I-17 ‘just in case.’ Oh, and did I mention the forested areas around the Flagstaff area? So combine poor climb performance, high altitude and high temperatures and trees, you have an almost immediate ‘pucker factor’ of exponential levels. Just climb baby, just keep on climbing I kept telling the airplane!

After about 15-20 minutes we reached our cruising altitude and I uttered a sigh of relief. From that point on the remaining flight back was uneventful- if you consider the temperature rise as we descended into the metropolitan Phoenix area uneventful.

Thank You Herman

A few days after the flight I held my next class meeting and Herman (eager to find out about my excursion), came up to me and asked how things went. Well, I gratefully acknowledged if it weren’t for his advice, it may have turned out different. I couldn’t thank him enough and with that, I knew I had learned a valuable lesson that day. A good pilot should always be very aware of EVERYTHING around him or her and keep in mind all weather conditions that can impact a flight. Too many pilots have learned that lesson the hard way. Herman’s sage advice remains in my brain every time the same scenario occurs. Stay safe out there!

According to Wells and Rodriguez, the majority of fatalities in aviation are due to commercial flights on final approach-and-landing, which experience hull loss (2004). In approximately 70 percent of commercial jet hull loss accidents, the main cause has been attributed to flight crew error. People are involved in every aspect of the aviation industry, creating a widespread problem with few sound solutions. Air Safety Week, a top newsletter devoted to news and the analysis of aviation safety, reported, “Among the leading cause of fatal accidents for U.S. air carriers from 1989 to 1996 were loss of control and CFIT (Controlled Flight Into Terrain). Human error was identified as a major contributing cause in a large percentage of these accidents.”(2009).

Aircraft cost millions, and sometimes billions of dollars, so why do aviation professionals make these costly mistakes? In short, they’re exhausted. Long hours in a high-stress environment for an extended period of time leads to fatigue in aviation. We have seen the effects of fatigue in aviation, and with the extreme growth in this industry, the problem will only get worse if not addressed. Air traffic controllers and pilots alike are being asked to push the limits of their ability as management tries to make up for the manning shortage. As we make leaps in technology, many safety program elements are focused on this new technology in the cockpit, to help the pilot make fewer mistakes. However, it should be noted that the misuse of new technology has been the contributing factor in some aviation accidents, and it does not address the underlying deep-rooted problem of human error due to fatigue.

According to the publication, Plain Language About Shiftwork, approximately 15.5 million people work shifts (1997). Working shifts disrupts the body’s natural Circadian rhythm, the 24-hour cycle in the biochemical, physiological or behavioral processes of living beings. Irregular hours, split shifts, and frequent rotations between day and night are common to members of the aviation industry, in addition to extended work hours and high levels of physical and/or mental stress. These Circadian disruptions are often accompanied by sleep loss, with the lack of sleep creating an environment where the individual is too tired to concentrate effectively, resulting in an increased possibility of error or injury.
Fatigue in aviation is also a contributing factor to human error. Fatigue has many causes, including shift-work, lack of personnel or manning issues, circadian disruptions, loss of sleep, long work hours, long periods of physical or mental activity, and fatigue is also a symptom of stress. As stated by Deputy Secretary of Transportation Mortimer Downey, at a fatigue management conference, “Fatigue, due to reduced sleep and irregular hours, has been identified as major factors in a number of crashes and costly incidents.” (2000).

The Body’s Normal Response to Stress

Dr. Peter Panzarino provides an excellent description of the process of the body’s normal response to stress.

A healthy human response to stress involves three components:

1. The brain handles (mediates) the immediate response. This response signals the adrenal medulla to release epinephrine and norepinephrine.
2. The hypothalamus (a central area in the brain) and the pituitary gland initiate (trigger) the slower maintenance response by signaling the adrenal cortex to release cortisol and other hormones.
3. Many neural (nerve) circuits are involved in the behavior response. This response increases arousal (alertness, heightened awareness), focuses attention, inhibits feeding and reproductive behavior, reduces pain perception, and redirects behavior. (2008).

Dr. Panzarino further explains how stress triggers the body’s fight or flight response:

• The combined results of these three components of the stress response maintain the internal balance (homeostasis), increase energy production and utilization, alter electrolyte (chemical elements) and fluid balance in the body. The also gear up the organism for a quick reaction through the sympathetic nervous system (SNS). The SNS operates by increasing the heart rate, increasing blood pressure, redirecting blood flow to the heart, muscles and brain and away from the gastrointestinal tract, and releasing fuel (glucose and fatty acids) to help fight or flee the danger. (2008).

The problem arises when there is no fighting or fleeing to help work those chemicals out of the body. In a natural environment, we would have to fight or flee, and the body would gear up and use those chemicals appropriately. However, in a stressful work environment, with no fighting or fleeing necessary, those chemicals remain in your system, effectively reducing your body’s ability to function properly. Under stress, the body produces cortisol to help meet the challenges of fight or flight. If your body is under high levels of stress consistently, the cortisol builds up in your system, causing damage.

How can we reduce cortisol levels, get a better night’s sleep and enhance our cognitive ability? Get a massage. Since the 1890’s, J.H. Kellog’s research on the effects of massage has opened the door for this luxury item to be realized as a necessary part of health maintenance (1897). However, despite the many documented effects of massage on the biological system, including improving sleep and increasing the ability to do both physical and mental work, it has not been applied to the aviation industry as a legitimate countermeasure to fatigue in aviation. A massage program has the potential to reduce the number of fatigue-related accidents by directly reducing stress and improving sleep. Also, because of the general reconstructive effects of massage on the body, overall healthcare costs for pilots will also be reduced. Understand the science behind massage and its application as a fatigue countermeasure, as well as other ways to fight fatigue will be explored in the upcoming Unsolved Issues: Part III – Working to Address The Problem of Fatigue in Pilots.
