1. If I save a situation after having flown, parked and shutdown the aircraft and then start s new session from "Load Saved Flight" menu item after restarting XP; yes.
2. No. It fixes itself if I click on: "Create New Air Frame".
3.I have saved situations at different airports with the same results (again, the parameters have to be the same as #1 and I fly 3rd party aircraft exclusively and have no problems with the other aircraft).
4. Currently, KPWK (my home airport), KCMI, KORD, KSNA and KBNAl One thing all those airports have in common is that they are 3rd party scenery. KPWK and KCMI are free downloads. The rest are payware.
FWIW, I have tried restarting the aircraft from the saved KPWK situation after moving it to another airport KLAX (a default airport) and no X's on the engine instruments. I'll try saving eh TBM at LAX and report back.
Thanks for sticking with this and the help.
