It should also be mentioned that a lot of those things that happen in the cockpit with regards to gauges and such are just animations, and don't really have anything to do with the mechanics of the aircraft. CloD actually simulates the engine, with pistons and fuel lines, not to mention the cooling system. A2A if very complex, but a lot of the switch clicking is just step#1->step#2->step#3. It's not like it's actually flooding the engine, just saying, "you did this too much, hence step#3 cannot happen until you do #1 and #2 again the proper way.

Or at least that was my understanding from what Oleg was hinting at months ago when people were complaining about not having clickable cockpits and some other options found in FSX.

Then again maybe A2A does all that stuff even though stock FSX doesn't.

You'd have to talk to the A2A devs and get them to explain it.
