The jet engine's complexity

An aircraft's jet engineWhy is it so complicated to become an air transport pilot?

A glance to the right side gives us some clues.
That complex thing is an aircraft's jet engine. Unfortunately, before being able to use one, we must have fully understood its principles of working. This implies looking in details at some technical points. And between the pneumatic, electrical, fuel or hydraulic circuits the ATPL (Air Transport Pilot License, the public transportation pilot's traffic code) is a really well stocked course. Especially for the "Aircraft General Knowledge" part.

A jet engine simply accelerates some air in order to produce a force that will push our aircraft really fast, allowing it to do its aircraft job: flying. However, it inflicts a cycle of operations to the ingested air that are not easy to understand, at all. On the menu we find some compression, combustion, adiabatic expansion and some theorems named after great scientists to explain all of this.

That is why the piston engine, propeller-driven aircraft suits me totally. It is easy to use and the working principle is just a bit more complex than for a moped.

But let's face it; I won't cross the Atlantic with a moped. This justifies the ATPL!
