Fatigue – you may win the battle, but you can’t win the war

November 26, 2014/in Personal stories, Tips and technique/by studentpltnews

I was on the return leg of a two-day trip to Texas last month on a late Tuesday evening. I had spent the entire week prior attending an industry conference in Florida. I’ll confess that like a lot of people, I don’t sleep well while traveling. The combination of a foreign environment, stress of the trip’s mission, and the seemingly impossible task of achieving a comfortable temperature in a hotel room, make adequate rest a futile effort in most cases.

I was fortunate enough to have only traveled across one time zone on this trip, in addition to getting what I would consider a normal night’s rest over the weekend in between. But the tell tale signs of fatigue were blatantly obvious in 20-20 hindsight which makes fatigue especially treacherous in that it may not be apparent until errors are made. I was flying a two-crew airplane with required “call-outs” and of course, checklist items to be completed along the way.

In addition to simply feeling tired, the next cue was a missed call-out. And then another missed call-out. And then a checklist item was overlooked that should have been part of my standard flight deck flow. Thankfully, in this case, an able and proficient pilot flying with me quickly picked up the omissions and pointed them out in a professional and courteous manner – an exemplary demonstration of good crew resource management principles. But had I not had the support of a second crew member, would I eventually have picked up on the oversight or would the mistakes grown in severity until it was unrecoverable?

The fact is that in our modern, information-overloaded lifestyles, everyone struggles with a general feeling of weariness or lack of energy and focus from time to time. And relief is nowhere in sight. According to the Center for Disease Control, 70 million Americans suffer from sleep deprivation which qualifies it as a certified public health epidemic.

Temporary bouts with fatigue (acute) generally have an identifiable cause and likely short-term solution. In my case, it was returning to my normal environment, free from the additional stress of an upcoming flight and fortunately, I visited the rehabs close to Tampa to help me get the detox I needed. The more dangerous scenario is the issue of chronic fatigue that develops gradually and diminishes not only your energy, but your mental capacity as well.

How fatigue effects the brain

Exacerbating the temporary fatigue induced by lack of adequate rest, traveling back to the Eastern Time zone as the sun began to set also led to a disruption in my circadian rhythm (internal clock). Circadian rhythms are produced by natural factors within the body with its main cue coming from light. As night fell, my clock was naturally telling me it was time to rest. Not an ideal scenario if you happen to be flying solo, single-pilot in preparation for the high stress, high-demand terminal environment at the conclusion of a long trip. You can see how the cards can quickly stack up against you.

While the effects of fatigue are different from person to person, and dependent on such factors as age and health, we’re essentially all hard-wired for eight hours of sleep per day. When you begin to dip in or borrow from those eight hours rest, it can’t be remedied by simply getting eight hours of sleep the next day. Fatigue effects are compounded by consecutive days of borrowing time from the vital sleep bank. In either scenario, you’re likely to experience some decrease in mental capacity. While the severity of fatigue impacts on the brain are difficult to predict, some of the alarming effects include lost memories, lack of focus and a higher propensity for risky decisions.

The National Transportation Safety Board (NTSB) is renewing its focus on the dangers of fatigue and its potential role in numerous aviation accidents. Fatigue is frequently associated with pilot error and seriously influences the ability to make effective decisions. Still, not enough is known about the dangers and research is being conducted to assist pilots in understanding the causes and effects which will, in turn, allow the aviation community to offer more defined guidance.

In the meantime, it would be easy to offer the recommendation for all pilots to simply achieve the recommended eight hours of rest and only fly during periods so as not to disrupt your own circadian rhythm. But that’s not necessarily realistic, so there are some things you can do to help stay alert.

From FAA’s Fatigue in Aviation, lifestyle recommendations:

Don’t…

Consume alcohol or caffeine 3-4 hours before going to bed
Eat a heavy meal just before bedtime
Take work to bed
Exercise 2-3 hours before bedtime. While working out promotes a healthy lifestyle, it shouldn’t be done too close to bedtime.
Use sleeping pills (prescription or otherwise).

Do…

Be mindful of the side effect of certain medications, even over-the-counter medications – drowsiness or impaired alertness is a concern.
Consult a physician to diagnose and treat any medical conditions causing sleep problems.
Create a comfortable sleep environment at home. Adjust heating and cooling as needed. Get a comfortable mattress.
When traveling, select hotels that provide a comfortable environment.
Get into the habit of sleeping eight hours per night. When needed, and if possible, nap during the day, but limit the nap to less than 30 minutes. Longer naps produce sleep intertia, which is counterproductive.
Try to turn in at the same time each day. This establishes a routine and helps you fall asleep quicker.
If you can’t fall asleep within 30 minutes of going to bed, get up and try an activity that helps induce sleep (watch non-violent TV, read, listen to relaxing music, etc).
Get plenty of rest and minimize stress before a flight. If problems preclude a good night’s sleep, rethink the flight and postpone it accordingly.

Some additional strategies for the flight deck to help stay alert…

lights on – consider, if your circadian rhythm dictates and flight conditions allow, keeping flight deck lighting turned up during cruise portions of flight with lights turned down at least 30 minutes prior to landing to allow the eyes time to adjust
human interaction – take a co-pilot or companion with you for conversation and to serve as a safety pilot
talk – consider filing IFR or taking advantage of VFR flight following so there is radio communication taking place and the additional task of switching frequencies
regular tasks to complete – assign regular tasks to be accomplished such as updating a flight log, rehearsing abnormal procedures or offering a pilot report
checklists, checklists, checklists – use a checklist and double check your checklist
conservative personal minimums – consider elevating personal weather minimums during periods of likely fatigues to reduce stress and workloads
caffeinate – caffeinated drinks can help alertness temporarily but take care to remain hydrated and remember the effects of caffeine can linger beyond the flight and disrupt rest

If you’re constantly battling fatigue, understand it’s a war you can’t win. There are some short term strategies to remain alert, but at some point a change in lifestyle, schedule or postponing a flight must be considered. There may also by underlying health issues leaving you more susceptible to fatigue including heart disease, obesity, sleep apnea and even mental health issues which will require a visit to a medical professional.

Regardless of the root cause, the effects of fatigue are real and the consequences too severe to ignore.

Top 5 mistakes you WILL make during your first 250 hours

November 17, 2014/in Personal stories, Tips and technique/by studentpltnews

None of us are perfect. I’m probably less perfect than most, but by the grace of God, good training and procedures, I’ve been fortunate enough to experience the joy of flight for more than a decade. Along the way, there have been many bumps in the road. A very smart instructor once told me, “You need to learn from the mistakes of other pilots because you may not live long enough to learn from your own.” While that may sound frightening to most people, there is a lot of truth in that statement.

While sitting around a hangar telling flying stories, I realized that many of us have made the same mistakes – sometimes more than once. I compiled a list of five mistakes that are common and can be very serious or even life-threatening if not managed quickly and accurately. Hopefully the worst outcome is a hand to smack the forehead of many pilots. Please heed the warning so as not to repeat what many before you have experienced.

Taking off on one magneto. This is much more common than I originally thought. Many of us don’t want to talk about it, but by a show of hands one evening, we found the percentage of pilots that have made the mistake of not having the ignition set to both magnetos to be very high.
Not retracting flaps after take off. So you got a sign-off for a cross-country flight. Lots of stuff going on and you take off, communicate on the radio, turn off the landing lights, turn to the correct on-course heading, start the trip/fuel timers, etc. And then you fly 38 minutes and while downwind abeam the numbers, you go to drop that first notch of flaps and realize that they are already down. Face palm.
Inadvertent flight into IMC. Normally, this happens because you are focused on something else besides looking out the front of the airplane. Common distractions include setting up the navigation radios or GPS, looking at the ground for reference maneuvers, or texting while flying. It’s going to happen. Keep calm and fly the airplane. Trust the gauges, engage the autopilot (if equipped), retreat toward alternate VMC weather and don’t be shy of asking for assitance.
Forgetting to remove chocks or tie-down rope. This is probably the most common. You do the preflight, but it’s windy and you need to run inside to get the window cleaner so you leave a chock down to keep the airplane from being blown away. Upon return, you’ve forgotten about the chock, clean the windshield, hop in and try to taxi. Wow, it’s taking a lot of power to get out of the wheel rut…[insert favorite expletive].
Landing with low fuel. The FAA’s definition of “low fuel” and mine are completely different. For VFR flight, you are only required by regulation to have 30 minutes of extra fuel on board. This is ridiculous and, in my opinion, ranks as the absolute WORST mistake you can make.
