This comes from a flight simulator experiment ages ago in the Boeing 737....
I'm on the runway. I engage the heading switch, followed by the altitude and thrust. The aircraft lifts off, although hardly in a clean rotation.
Now I'm wondering: While it did work in the flight simulator, will the autopilot follow these commands in real life as well if I repeated this in a business or commercial jet?
Is there anything stopping the autopilot from engaging a specified altitude or from following instructions which are utter nonsense?
