Update: this seems to only happen if the aircraft is loaded with the engines not running (cold and dark). If the engines are running, i.e. load another aircraft, start the engines, then load the CS 757 then the ADI is normal.

While it may seem like this is solved, I do not believe that I should have to load another aircraft and start the engines every time I wish to use the CS 757. Call me silly, but I think the CS 757 should load correctly from a cold and dark save file.

I know, I can be so unreasonable!  :-/
