15/07 Human factor in aviation
Plane is being flown by human. And a human can make a mistake. It is a fact, and world aviation knows that perfectly well. Among the most common worries of people with fear of flying – there is a probability of a disastrous air crash just because of mistake made by some unknown person, sitting in a cockpit. Let’s see are these worries backed by actual facts. It’s obvious that among 140 000 flights, which are being performed every day, there is at least 1% of pilots, who make some mistakes. This is because each of us can mistake, including the pilots, who are as well as You fall into the category Homo Sapiens, and they just can’t ALWAYS work faultlessly. It is evident. And it’s also evident that if every mistake made by pilots led to dire consequences, then there would be 1400 air crashes every day by a reason of human factor. But it doesn’t happen.
Therefore, aviation is well prepared for the possibility of human mistakes, and it’s organized in such a way that allows preventing fatal results in case of mistake made by some pilot of crew. In what way? Owing to a system, that is called «Cross-check» in aviation. The system a priori SUPPOSES a probability of mistake by some or other crew member, that’s why each action, which is being performed by one person (whether it is a flight attendant, or pilot, or serviceman), should be rechecked by another one. For example, a flight attendant, closing an entry door of plane before its taxiing, always rechecks the door on the opposite side, closed by the colleague. And conversely, the second flight attendant rechecks the door, closed by the first one. After which smart electronics of the plane rechecks that both of them really closed the doors. And only after that a captain will get a message about the doors readiness. And the same goes for everything, from the easiest processes to the most complex ones in aviation: people recheck each other, and then electronics rechecks them. Such checkout system leads to detection of any mistake on a stage, when it can be corrected, not posing a threat to a flight safety. People make mistakes and aviation is well prepared for that. Nowadays none of human mistakes leads to an air crash. Of course, even such super-reliable control system, which is being operated by several people and computers, can’t be ABSOLUTELY faultless, as well as NONE OF ANY OTHER systems in the world. But nevertheless, specifically in aviation, while being on a board of plane, your safety is higher than in any other process of human life. Don’t forget that human factor is present not only on planes, but also on the ground, and in a much higher degree. But in aviation all human actions are being controlled, and not once, minimizing the probability of fatal mistakes, on the ground our lives often depend on the uncontrollable activities of other different people.
