Hello, I am new to this forum and I was wondering where I could find information regarding FS2004 Flight plans. I have imported some Hi quality DEM scenery and textures into the sim but I would like to have it so that one could create a flight starting at these locations. These locations are actually mountain passes. I would like to make it so that when I am at the created flights section in MSFS I can create a flight starting in mid-air at various points in the mountain passes.

I've never tried it, but I suppose you could use AFCAD to create a phantom airport at the latitude, longitude and altitude you desire. You'll have to do some quick piloting to get your speed up and gear retracted, because there won't be a runway to hold you up, but if you start high enough it should work.You could also just fly to the point where you'd like to start your flight and save the flight. They when you restore it, you'll be where you want to be, with the right airspeed and aircraft configuration.
