An aircraft is not an isolated entity within the environment; airplanes, helicopters and so never fly on their own but are managed by crews, are under the jurisdiction of regulations that work within vast systems in which many different organisms and people take part.
Aircraft are being repaired by technicians and mechanics, designed by engineers, they carry cargo and passengers and indeed, suffer the consequences of the advance of technology, business trends, polices and politics.
All aircraft, from the simplest to the most complex are affected by human behaviour.
In all these different facets of the vast international aerospace community the actions of all those persons implicated become the consequences of the operation of the whole system as well as the outcome of each individual flight; in other words, what we are becomes what happens as we fly, either for good or not.
The science known as human factors studies how our behaviour translates into attitudes that must be taken into account in our activities, and particularly in those that like aviation, entail responsibilities over lots of lives and huge amounts of money. Within the aeronautical realm what we do really matters, as well as who we are and what we think.
Understanding human nature is fundamental for getting a grasp on how aircraft fly safely and how to increase security and survivability. Thorough the links that you will find at this page you will be able to access several articles and essay on his topic.
Dozens of people take part directly or indirectly in the control and preparation of each flight, and all must be accounted for.
