FLIGHT SAFETY :: PILOTS, IT'S YOUR DECISION

Most accidents are the result of the pilot's actions. This includes their skill level and, most important of all, the decisions that they make. This section details some of the factors that can affect how the pilots decisions do - or don't - keep the aircraft in one piece and the occupants safe.

TO GO OR NOT TO GO

a Weather
Probably the single most important factor in Microlight flight safety is the decision of a pilot to begin, or to continue with a flight, in unsuitable weather conditions. As you might expect, weather was a major factor in fatal accidents: over 80% of Controlled Flight Into Terrain (CFIT) accidents happened when the pilot either continued flying into adverse weather, or did not appreciate the actual effects of the weather conditions. Crosswind landings seldom result in fatalities, but they still feature in many accidents resulting in broken aircraft and painful injuries. Remember that weather does not stay constant, it doesn't always do what the forecast predicts, and it can deteriorate very fast. Respect the weather, and the implications for flight safety. That doesn't just mean other less experienced people who can't fly so well are the ones who should respect the weather; it means you.

b I Can't Turn Back Now!
Any competent pilot knows that weather can, and will, change enroute. If it does, it is essential that the pilot is prepared, and willing to divert or turn back if conditions deteriorate. It does not reflect badly on your ability as a pilot if you turn back in poor weather, in fact, it reflects good judgement and realistic assessment of the situation. It is also important that diverting is feasible in practical terms. Have you got enough fuel?, money to get home, or pay for a hotel? Have you promised to be somewhere important? Never put yourself in a position where you would not feel able and willing to turn back if necessary. No Monday job is worth dying for on a Sunday, so carry your driving licence and credit card. The decision to turn back will be made easier if you have practised, in advance, to fly the relevant manoeuvres on instruments, for example: a 180% turn and if necessary climb to a higher Minimum Safe Altitude (MSA).

c Chain of Events
In aviation accidents, it is common to find a chain of events where one shortcut or poor judgement leads to another. For example, the apparent 'cause' of an accident may be that the pilot has attempted a landing in marginal weather conditions, has not diverted or turned back despite reducing visibility, or has descended below the Minimum Safety Altitude (MSA) to try to establish their position. Consider why they chose to do this - was it really an isolated bad judgement, or could they have been short of fuel due to poor planning and lack of contingency time?.

NOTE: This MEF of 1700 ft is higher than you might expect because masts of 300 ft or less are NOT shown on the chart. MSA is at least 1000 feet above the Maximum Elevation Figure (MEF) in the relevant chart lat/long square. Remember that good planning, proper use of forecasts, awareness of terrain features en route and relevant safety altitudes, are not just good practice - they save lives.

d But I've Done it Before!
Why do some highly experienced pilots believe that they can safely fly in marginal conditions, ignore their MSA, or attempt extreme aircraft manoeuvres? One of the reasons could be that either they, or others that they know, have done it before and 'got away with it'. This may well be true, but it certainly does not prove that it is safe. Imagine if your son or daughter tried to convince you that it was quite safe for them to cross a busy road blindfold, because they did it yesterday, and survived? What would you say to them?

e But I Know Someone Else Who Does It!
People vary in all kinds of ways, experience, concentration, skill, how they are feeling on a certain day, how much sleep they had, how much sleep they need, the after effects of recent illness, and their personal or domestic circumstances. The fact that someone else, on a particular day, can land in a marginal crosswind does not mean that you can necessarily do the same. The fact that you can do this does not mean that you should encourage someone else to do the same. Being a competent pilot means correctly assessing your own limitations on a particular occasion. It does not mean pretending that if someone can do it, then everyone can do it every time; or that if someone else is doing it, that necessarily makes it safe or wise.

f Exercising Sound Judgement
Pilots enjoy a great deal of freedom, despite the unforgiving nature of flying. The reason for this is that the regulatory authorities place a great deal of trust in the pilot to exercise competent judgement concerning flight safety. Qualified pilots are thought to be capable of making responsible decisions about whether it is safe to fly, taking into account their experience level, aircraft type, location, personal physical and emotional state, and prevailing or expected weather conditions. There are two serious threats to the use of this judgement: if the pilot himself has an excessively optimistic view of the situation or of his own ability; or else, is persuaded by other people to proceed with a flight against his better judgement. How can this happen?

g But You Promised!
Never promise to fly on a certain day or to be somewhere important, if you can only get there by flying. If it really is important to be there, leave yourself time for alternative surface transport. Tell friends or relations that you may be able to take them flying weather permitting. Better still, keep it as a 'surprise', decide on the day if you feel prepared and fit, the weather is fine, and the aircraft is serviceable, and offer to take them flying. They won't know that you had to book the aircraft a month in advance. It is always disappointing to cancel a flight if you have nonaviator people, especially children, looking forward to the trip. This is particularly true if the reasons are not easy for them to understand.

h Peer Pressure
There will always be people who will pressure you in subtle ways to take risks that you don't feel comfortable with. They can be prevalent in clubrooms, asking you if you flew on a certain windy day, and smiling smugly if you say that you cancelled whilst they braved the crosswind, low cloud or lack of horizon. 'You diverted? What an idiot! I'd have carried on and got there...'.Perhaps they would; alternatively they might have carried on and not got there. Perhaps they are just full of bravado and wouldn't have carried on at all. Perhaps they have more experience, a better equipped aircraft, or suicidal tendencies. It doesn't really matter. The fact is that the world of aviation relies on competent and independent pilot judgement, and the pilot is you. If you are swayed by clubhouse buffoons, then you are more afraid of their dubious opinions than of your own death. If this applies to you, you may not have the character that is expected of a pilot licence holder.

i Audiences: Are You Impressing Anyone?
In the review of fatal accidents, more than half of the low flying and aerobatic accidents involved an 'audience' - seldom at a formal airshow, but more often to impress friends on the ground, at the clubhouse, or even passengers taken for a flight. The temptation to 'show off', to impress those watching, proved fatal in too many cases. (In fact, the 'audience' are not necessarily filled with admiration while watching these antics. They may simply be wondering when the accident will happen, and what this person is doing with a licence.) Before you decide to take such a risk, ask yourself: would the people who are watching be prepared to risk their lives to impress you? What would you think of them if they were?

j Joint Decisions
It is a well known phenomenon that a joint decision made by a group of like minded people is usually more extreme than the decision that any one of them, alone, would have made. Pilots tend to be, by their nature, fairly adventurous individuals who are willing to face a certain amount of risk in order to pursue their activities. Committee decision: 'we'll give it a go!'

DIFFERENT RISKS FOR DIFFERENT PEOPLE

a: Age Groups
The review of fatal accidents suggested that the risks for young pilots were a little different from those of more mature years. Young pilots - especially young male pilots - sometimes took quite unnecessary risks in terms of low flying and aerobatic manoeuvres, often in front of friends or others watching (see'Audiences' above). Older pilots seem less tempted to perform spectacular or risky manoeuvres, but they may take a different kind of risk. Pilots who fly into terrain, under full control of their aircraft and without any significant technical failures are, on average, older than pilots involved in other kinds of fatal accident. Typically, these pilots continued flying into adverse weather conditions, and / or ignored their MSA (if indeed one had been calculated).

b Total Experience Level
Pilots involved in the fatal low flying and aerobatics accidents are usually highly experienced. Perhaps they believe that because of their very high hours, they can fly safely in these very unforgiving regimes. Pilots in fatal CFIT accidents are also typically very experienced. Again, they may believe that their long experience might allow them to fly safely in conditions that others are advised to avoid. If this thought ever enters your mind, remember that all of those highly experienced pilots in the fatal accident reports also thought that 'it would be all right'. Pilots with low flying hours may be vulnerable to a different kind of accident. Those with very low hours feature less in the accident reports than those with 200 - 500 hours. The latter group seem to be more likely to lose control of the aircraft during visual conditions. This is probably not very surprising, given that these pilots are still quite inexperienced, and may be moving for the first time toward some slightly more ambitious flying.


c Use It or Lose It
Recency may also be a safety issue; the fact that you could do something perfectly six weeks ago does not mean you can immediately do it now. A skill is like a message written in chalk on an outdoor wall - it gets eroded a little every day. If the writing is retraced repeatedly it will become more enduring. Even then, it will be eroded eventually if it is not periodically refreshed. Skills are refreshed via practice, annual or recency checks or post qualification training.


ONLY HUMAN

a Trust Me, I'm a Pilot
Despite what some people may think, pilots are only human, and have normal human limitations. The fact that pilots are trained, experienced and competent, does not mean that they will always perform perfectly, that they will never experience an 'off day', overload, illusions or distorted perceptions, or that they will never make a mistake. Everyone recognises that physical parts of the aircraft have a certain expected failure rate, and this is (correctly) seen as a realistic, normal performance level. Human pilots also have a 'realistic' performance failure rate, and it is not zero.

b To Err is Human
One characteristic of human beings is that we all make mistakes, no matter how well trained, competent, careful, or skilled we may be. Nobody is immune from errors, and the person who imagines that they are infallible is the most dangerous of all. There are two general classes of error:

  • 'slips and lapses' include 'finger trouble', errors in data entry or recording (such as writing down the wrong digits), or not noticing that an instrument reading has changed;

  • 'mistakes' refer to actions that the pilot makes intentionally, and executes correctly, but they turn out to be a bad plan.

In general, mistakes are more easily reduced by training, but they still canand do happen. The important thing is to recognise and rectify mistakes - and to learn from them. Slips and lapses can happen to anyone and
are, if anything, more likely in highly
skilled, experienced people.

c Believing is Seeing
There are well known optical illusions that can affect pilots judgement, eg. height perception when approaching sloping runways. In other circumstances, there can be a mental distortion that is nothing to do with visual illusions as such, but
can be just as dangerous. Human beings are selective about what they 'see'. If a person believes something to be true, then they will tend to 'see' only those cues in the environment that are consistent with that belief, treating these as positive confirmation that the belief is correct, and 'not see', 'blot out' or ignore any evidence to the contrary. Unfortunately, pilots are no exception to this rule. If a pilot has formed the belief that he is at a certain geographic location, then his mind may try to organise whatever cues are present in a manner that will confirm this belief. This means that conscious cross checking to look for differences to expectation are critically important, and frequently a
feature of aviation procedures. This principle can even apply to the expectation that instruments should be showing a certain reading, or hearing an ATC clearance that is expected or usual. It is vital that instruments are actually read and
messages are really listened to, with at least some anticipation that they may not say what you expected. It is
difficult for anyone to accept this about themselves, especially if they are highly technically qualified and experienced. Believe it: if you are human, this does apply to you.

d Stress
Stress is a familiar feeling to most people. When people are stressed, their judgement can be affected, and their thinking may be unclear. They may suffer from 'tunnel' thinking, concentrating on (or over-reacting to) one particular problem to the exclusion of all else. This is dangerous. If there is a problem in flight, the pilots first priority must be
safe flight. Attention to a faulty radio, airsick passenger, or navigation problem must be a secondary task. If you are feeling stressed before a flight, consider whether you should cancel. If you can foresee a period of high workload during the flight, rehearse it mentally, prepare as much as possible ahead of time and, above all, remember that your first priority at all times is to fly the aircraft.

ONLY A MACHINE

a Trust Me, I'm Electronic
Just as human beings can make errors, mechanical and electronic devices can also be faulty. THINK about what your instruments should say - do a mental 'reality check'. Always cross check with a second source (e.g. landmarks in the outside view) if possible. Change - especially movement - attracts attention from our senses, but a static condition, or a
very slow rate of change, is more likely to go unnoticed. It is important to check all instruments regularly, never think that your attention will automatically be drawn to a deteriorating situation. If your fuel gauge is stuck on full, the needle will remain steady, although actual fuel levels will be dropping. There will be no rapid movement or change to attract your attention.

b GPS
GPS is becoming a common accessory for GA pilots. It can be tremendously helpful at times and is probably an overall safety 'plus'. However, a few words of caution:

  • Never use GPS as your primarymeans of navigation
  • Never use it to land in poor visibility
  • Never spend time head down, fiddling with GPS, and not watching the outside world.
  • Never believe GPS data without question. It is NOT infallible and it CAN go wrong.
  • Never fly in conditions that you would normally avoid, because you believe GPS will reduce the risk and get you there safely.

SUMMARY

Most pilots want to enjoy the freedom to fly when, where and how they want to, whilst maintaining safety for themselves and others. The way to achieve and sustain this situation is to:

  • be realistic about the weather
  • work out a Minimum Safe Altitude (MSA) and keep to it
  • use your judgement responsibly,
  • don't be pressurised to fly
  • know your own limitations
  • prepare thoroughly
  • allow for contingency
  • have enough fuel
  • be prepared to divert
  • rehearse for possible 'situations'
  • use good practice in your planning and flying
  • don't take unnecessary risks.

This will avoid the need for additional regulations and restrictions, and give you safe,enjoyable flying.
