There is a button combination you can press that automatically starts up the plane and all needed systems. There is also the option in missions to start from the runway with the plane already started and ready to go.
Hope this answers your question.

Complex in two ways. One - more buttons and modes and switches. If the pilot needs to click 3 buttons to get a weapon up and running, YOU need to click those same buttons. Two - flight model. Load your aircraft odd and you will see the effect once you get up in the air. Load your aircraft symmetrically but fire all weapons from one plyon and you will see the effect as well.
As for learning the system, it takes a few hours to master but once you got the sequence down, it'll be second nature after a few flights.
