Top 10 Pilot Errors
Here’s a smart way to look before you leap
onto the next flight
By David Ison

One of the most disturbing sta-tistics
about general-aviation accidents is that more than 75% of them are made
because of pilot error. Considering that it’s unlikely that pilots are
going away anytime soon, the solution comes in the form of prevention.
Saying this is easy, but actually making progress toward this goal is
rather problematic.
The first step toward eliminating pilot
error is to examine the enemy. Just what types of errors are pilots
committing and why? Then, armed with this information, pilots can make a
concerted effort to avoid such mistakes through a fusion of training,
planning and keen attention.
There’s a common misconception that critical pilot errors occur only
during flight. A surprising number of accidents result from inadequate
preflight, like using checklists and forgetting to fasten the cockpit door
(above). They’re small mistakes that could escalate into a series of big
ones.
1
-
Weather. The more a pilot knows about
it, the better. While thunderstorms,
icing and winds claim their share of airplanes, the real weather gadfly
are those serene, innocent-looking clouds and their cousin, fog.
Clouds and fog aren’t inherently dangerous; it’s just that when pilots fly
into them, they don’t know how to fly on instruments. They fly into a
cloud, lose control and crash. Accident gurus call this flying “VFR into
IFR.” Well over 80% of such accidents are fatal.
Even though these accidents are referred to as “inadvertent flight into
instrument meteorological conditions (IMC),” only 24% of them are
inadvertent. The remaining cases show pilots who continue into poor
weather. Why is this? Overconfidence is one. Some believe that they don’t
need to stay current or that their hour under the hood is good enough.
Social pressure also plays a role. Passengers want to get there and
pressure the pilot to continue. Last, there’s “get-there-itis.” Pilots are
mission-oriented, sometimes too much so.
2
- CFIT.
Another common pilot error that often involves weather is controlled
flight into terrain (CFIT). A simplified
definition of CFIT is “flying a perfectly good airplane into the ground.”
If a pilot is in a cloud or in fog, he or she can’t see the ground. If the
pilot isn’t doing a good job of keeping up with the terrain, an unpleasant
meeting with the ground is more likely. Another time when CFIT can be a
factor independent of weather is at night. Pilots seem to have a knack of
flying into trees and hills after the sun goes down. Again, if pilots
allow themselves to be lulled into neglecting to constantly compare their
present altitude to that of surrounding terrain, the outcome is likely to
be nasty. If you can’t see the terrain, you must be able to point to your
position on a sectional, en route chart, approach plate, etc., or you
shouldn’t be flying.
3
- Poor Communication.
Another boo-boo pilots seem to have an affinity for involves deficient
communication. This difficulty of
communicating comes in several forms. When dealing with air
traffic control (ATC), pilots tend to hear what they want to hear. Good
pilots anticipate what is coming next, including ATC instructions,
however, this profound skill can trick the mind into “hearing” what is
expected regardless of what actually filters into one’s headset. Also,
misunderstandings between ATC and pilots happen all the time. This plays
into the most knotty communication quandary of all: the lack of
communication. It’s silly that a pilot would rather keep quiet than ask
for help or clarification. If there is any question on what was said, ask
for elucidation. It’s amazing how shy pilots can be when it comes to this
simple task. Don’t fall into this trap. It’s better to find out you’ve
misheard something immediately rather than finding out your license is
going to be suspended later.
4
- Low-Level
Maneuvering. If you ever hear the words “watch this” from a
pilot, look out! Pilots are notorious
show-offs. How many times have you heard about the pilot who
performs an impromptu air show for friends and significant others? A few
low-level maneuvers later, and the plane is falling out of the sky. Some
air show. The problem isn’t just that pilots are flying low to the ground;
it’s this combination of flying too slow and in too tight of a turn that
causes crashes. Of course, adherence to the minimum safe altitudes laid
out in the FARs is a much smarter practice. If you do actually
find a legitimate reason to fly close to the ground, fly the plane like
you do when you’re close to the ground at other times, like during
landing. Monitor your speed and your bank angle. You certainly wouldn’t
try a 60-degree bank turn with no flaps at a very slow speed when turning
base to final, so why do it over your parents’ or friend’s house?

-
Inadequate Preflight Inspections. It’s amazing how many pilots
mess up preflight inspections. A cursory
walk around simply to “kick the tires” so you can hurry up and “light the
fires” is beckoning for trouble. Take your time during your
preflight. If you find yourself inspecting in haste, slow down. Take a
comprehensive look at everything, with checklist in hand, to make sure you
don’t miss anything. When you finish, scrutinize the details. Take one
last waltz around the airplane, looking for anything that jumps out as
being amiss. Perhaps a door isn’t flush with the fuselage or there is
still a red, waving flag-looking apparatus on the pitot tube. It might
sound funny, but there was actually an occasion when a pilot neglected to
unhook a tail tiedown, which was connected to a concrete block. The pilot
wondered why the plane required so much power to taxi and why it had an
inexplicably aft center of gravity in flight. Luckily for this pilot, he
was able to live to tell his story.

-
Inadequate Preflight Planning. Renowned classical novelist
Miguel de Cervantes wisely said “forewarned forearmed.”
Those who are prepared are equipped to
deal with the tasks at hand. Typically, the level of preflight
preparation is proportional to how smoothly the flight goes. Think about a
time when you rushed your flight planning and how it came back to haunt
you later. Often, pilots take off with no planning whatsoever. That’s when
they have a tendency to get tangled in temporary flight restrictions or
nasty weather. Countless pilots neglect to check density altitude, even
though they’re planning a departure from a short strip with a field
elevation of 6,000 feet on a 100-degree F day. Weight and balance also is
something that often is dismissed. But how can you know for sure you’re in
limits if you don’t even bother to check?
7 -
Failure to Use a Checklist. Lots
of pilots get into the mindset that flying is like riding a bike—something
you can do easily out of memory. While
it’s true that 99% of the time, you’ll remember to do everything required
of the checklist, it’s that remaining 1% of the time when you forget to do
something that will bite. You can make sure you complete
everything you need to all the time if you consistently use a checklist.
Sure, you can do cockpit flows or whatever other technique you like, but
back up your actions with a checklist. And don’t just blindly read it. As
you go through each item, verify that the handle is in the right position
or something has actually been accomplished. Just think of the number of
gear-up accidents that could have been avoided if the pilots actually ran
the before-landing checklist (hint: all of them!).
8
- Failure to Perform
the “I’M SAFE” Checklist. Another common error of pilots is
forgetting to use the “I’M SAFE” checklist.
For those who have forgotten what the
letters stand for, here’s a reminder: Illness, Medication, Stress,
Alcohol, Fatigue and Emotion (some say E is for Eating). Sick
pilots have no place in a cockpit. Can you fly with a cold? Maybe, but
you’re more susceptible to spatial disorientation, you could have a
painful run-in with a blocked eustachian tube or just feel so blah you
make stupid mistakes. And don’t be tempted to hide your illness with
medication and then go flying. There are lots of over-the-counter
medications that can make you a zombie. Of course, illegal medications
shouldn’t be in anyone’s blood, let alone a pilot’s. You’ve got to make a
choice—fly or take drugs—you can’t do both.
Stress is commonplace in our fast-paced world, but there is a point at
which it becomes so intense that it’s a distraction. If you’ve got to go
to divorce or bankruptcy court in the morning, it’s probably a good idea
to reschedule today’s flight. When your mind is outside the cockpit,
you’re bound to make mistakes. And there certainly is no time that your
mind is farther outside the cockpit than if you’ve been drinking. The
effects of alcohol obviously are detrimental to good cockpit decision
making, and alcohol can affect your flying ability, even though you don’t
have any booze left in your blood. Hangovers are essentially just like any
other illness; if you have one, don’t fly.
Fatigue is a somewhat underrated no-go
item. Many of us have flown when we’re not at our peak performance level.
Alas, fatigue goes hand in hand with red eyes and transoceanic flights.
But there are things that pilots can do to mitigate fatigue. Being well
rested by planning ahead makes a big difference. If you know you’ve got a
5 a.m. flight, you need to go to bed early. It’s a no-brainer, but pilots
weaken their minds through a lack of sleep all the time. Emotion, just
like stress, is something that everyone has to deal with, but there are
times when this, too, is at a level that is intolerable in a cockpit. If a
loved one just died, cancel your flight. Your mind won’t be in the
cockpit, so keep the rest of your body out of it, too. Finally, make sure
you’ve eaten something and stay well hydrated. A physiologically sound
pilot makes better decisions than a hungry, thirsty one.
9 -
Running Out of Fuel. It truly is
unbelievable how many pilots run out of fuel every year. It’s interesting
to note that most of these incidents occur not because, say, the fueler
didn’t put enough gas on board. Instead,
pilots try to push it just a little bit too far, running out of gas just
short of their destination. That darned “get-there-itis” bug
tends to afflict pilots all too often when it comes to fuel. Who wants to
make an extra stop, anyway? But that 30-minute fuel stop is better than
the one you’ll have to make when your tanks go dry.
The problem with fuel management is pilot
mentality. Pilots think of fuel in terms of distance, particularly if,
during their planning, they determined the flight could be made with the
amount of fuel on board. Instead, fuel should be thought of in terms of
time. The best way to implement this philosophy is to determine how much
fuel will be available once you’re airborne, in hours and minutes. Of
course, an allotment of fuel should be set aside for time to divert, then
a little more for reserve. Upon departure, a countdown timer should be
started. When the clock expires, you land. No ifs, ands or buts about it.
This alleviates the problem of changed groundspeed due to wind and helps
give pilots a mental excuse to land short of the destination.
10 - Mismanagement
of Technology. Scientist and novelist C.P. Snow once said that
“technology is a peculiar thing. It brings you great gifts in one hand and
stabs you in the back with the other.”
The mismanagement of technology is a pilot error that has come under
particular scrutiny lately, as glass instrumentation has quickly been
invading the cockpits of general-aviation aircraft. There is much
debate concerning whether modern cockpits augment or diminish safety. But
the fancy equipment is not to blame; it’s the pilots who don’t manage
their resources properly that cause exigency. What often happens is that
pilots don’t take the time to learn the equipment thoroughly. When the
glass does something a pilot hasn’t seen before or something needs to be
changed quickly, too much concentration is focused on the avionics. What
suffers is situational awareness and, more alarmingly, aircraft control.
The accident data says it all. According to
the statistics, pilots have the cards stacked against them. But they don’t
have to sit idle. Alternatively, pilots can be proactive to reduce risks.
They can immunize themselves against common mistakes. Keeping a careful
watch, pilots can intercept error chains before they go too far. As
President George Washington wisely said, “timely disbursements to prepare
for danger frequently prevent much greater disbursement to repel it.” With
each bit of extra effort, pilots will, no doubt, increase the safety of
flight.

Pilot Deviation Safety
Tip
Notice Number: NOTC2038
AIRBORNE PILOT
DEVIATIONS
What is an airborne pilot deviation? The actions of a
pilot that result in the violation of a Federal Aviation Regulation while
in flight. Such deviations could result in a loss of separation between
your airplane and another or with the next mountain peak!
Why do pilot deviations happen? Pilots don’t start off the day by saying,
“Today I’m going to go out and commit a pilot deviation.” We don’t say,
“I’m going to fly through some airspace that I’m not supposed to.” No,
pilot deviations occur because of poor technique, inattention, or failure
to plan properly.
The FAA Safety Team wants airmen to be aware of this problem, and
encourages pilots to increase their awareness and skills so that aviation
safety is enhanced.
Types of IFR Deviations (Listed in order)
- Altitude violations - Failure to maintain the
assigned altitude
- Course clearance violations
- Airspeed violations
- Missing a compulsory reporting point
What can be done about it?
- First, have a method to remember and record
directions and/or clearances from ATC, and second, execute the action.
For example,
- Write it down,
- Input it into an altitude alerter or avionics
system, or
- Index the heading bug
- Use current directories, charts, approach plates, and
data bases
- If ever in question, call ATC and confirm
Types of VFR Deviations
(Listed in order)
- Airspace violations - Flying into airspace such as
class B, C, D, prohibited, restricted or TFR’s without communication
and/or clearance
- Flying VFR into IMC conditions
- Low level flight
- Required aircraft equipment is not installed or
operating
What can be done about it?
- Improve flight planning - Know the route and
requirements
- Have only current directories, charts and data bases
onboard
- Obtain better/complete weather briefings
- Obtain the NOTAM’s and TFR’s for your route of flight
Plan ahead and be precise in your preparation for flight
and in your actions while operating the aircraft. Don’t become complacent
or make assumptions. Always be alert and aware and continually processing
the situation. Ask yourself, “Do I really have everything correct?”
