Soon after the first machines successfully lifted off it was time to think about the safety of the pilot and later of the crew and of course the passengers.
Time went by and travelling with airplanes became much more affordable, and since there were more and more airplanes in the sky, it was absolutely necessary to improve the safety.
And safety goes side by side with the electronics.
The word avionics, fused from aviation and electronics, is being used whenever electronics in the airplane are concerned.
This reaches from the navigation to the weather systems.
The most important part of the avionics is probably the collision-avoidance system which is based on a system, that can detect nearby airplanes.
Certainly one of the most important innovations in the modern aviation and now absolutely non-expendable.
Another part of the avionics that hast to be regarded as non-expendable is the already mentioned weather system.
Composed a strong radar and an anti lightning system it is a reliable guid through the night.
Often tested by the military and considered approved, the avionics used in airplanes nowadays provide perfect protection and make it very safe to travel by plane.
The avionics in general are probably the most amazing improvement as far as the whole aviation industry is concerned.
Even though the perfectly calculated shapes of the modern planes are very remarkable, the most astonishing part will always be the fact, that mankind did after all find a way to fly all around the globe.
The fact that a lifeform managed to free itself from the given options is the real amazing part of the whole history.
It will be interesting to see how this will evolve in the future and how the masterminds will solve new problems like the lack of oil resources.
That will probably have to be the next step in this process.
