I'm flying from ams to yyz and wanted to do the flight in legs and save the flights in mid-air. I read the manual on how to and it said the computer should automatically create files. The computer won't and I cannot load a panel state

When you load the 777 in the air once again on the flight it will load up as it was before. It will take 30 seconds to initialize and until then you need to control the plane manually. Also it will load up only if you have a flight plan imported to the flight plans folder of the 777
