I have my default flight as the MS C172 (engines running etc) as everyone should (or the MS microlight)

If I/you just load a flight from any airport and ramp, I find CS 707 shuts its self down to a almost Cold and Dark state.

ATM and with it being a 3 man job IRL its one of the very few aircraft I don't start myself, as a Captain in the 707 just flicks the fuel cut of to on IRL, the FO and engineer do all the hard work.
So in the 707 so far its a Ctrl+E for me and the FO and engineer start her up perfect every-time.
All I need to do is turn the air-con on after.

So try not shutting down the C172 trust the 707 to do it, fsx hates switching aircraft when one is complex
