Hi all,

I know this is an old thread but I've just been seeing what I can do with Plan G and the autopilot in FSX, and I thouhgt this might help someone.
So as stated above the export to FSX doesn't include the passing altitudes, but only the cruising altitude.

If someone is new to FSX (or coming back after a few years like me!) you might note that the Autopilot (certainly on the Baron) doesn't use the Flight plan's cruising altitude setting.  You need to set the climb rate and the desired altitude yourself.
I think this also depends on which aircraft you're flying and also the navigation mode you're using because ILS descents work correctly. 

Cheers,
Phil
