The problem is that no matter the altitude of the flight plan, the ATC Clearance always give me 10000 or 11000ft even if the cruise altitude of my flight plan is 36000ft.
In the FAQ document I read :
Quote: Whenever I create an ADV Flight File the cruise altitude is always wrong (too low) and the cruise speed is showing a ridiculously high value.
A: Start ProFlight and select the Select Spec option to check the cruise speed set for your aircraft. Check the MACH setting is valid. ie. Mach .74 should be entered as .74 and not 74 (If you have a missing decimal point your ADV Flight File will be wrong.)
That´s another problem since Proflight always back the speed to 74 after changing the correct mach value and the problem with the altitude continues.
