there would be box to check and uncheck under the (options--> flight) buttons for those wanting these options or not, much like the governor, auto take off, no tracer, and track ir options. so the many of us would love these extra and use them. but the game could still be gamy enough for thos that don't want the hassle.
I personally would like to see fuel mixtures and gyro scopes ingame, at least the option for them to be used.
