Had the same problem, ended up loading the "Ready to fly" profile, moving the plane to my airport and going through the complete shutdown. After saving it now works ok!

I have it, but I stopped using it a long time (18 months or more) ago.

Hi, everyone,

I just did the following and it produced a reasonably good C & D state:

Open FSX, choose a default Cessna as the aircraft, go to a heavy gate at the airport of your choice.

In the Cessna, shut down everything, including engine, master battery and avionics switches, lights, but make sure pitot heat is on.  

Load a 777.   Save it, and the next time you start FS, load that flight and then switch to the airport of your choice.   It should be in a reasonably good C & D state.  The hydraulic switches for the flight controls should be on, so the flight controls will work once you get the aircraft started up. Usually the ADIRU switch is on, so just switch it off.   I'm not sure what state the pitot heat will be (there's no switch for it in the T7), so if you experience strange airspeed indications type Shift-H to turn it back on.
