I have FL340 from KLAX to KSEA in the Fs9 Flightplan and the altitude set in PF2000 but I get FL350 in the PFE flightplan? The direction of the flight requires an even altitude. I have deleted and and re-entered the flightplan serveral times to see if it would change. It does not.
I did that, just wondering why the different altitude.
Proflight2000 was written before RVSM was generally in use, so uses the format generally prevailing before then :Eastbound FL290/330/370/410 Westbound FL310/350/390. It will change your FL during the compile. As Dave said, you can change this in PFE before connecting to the sim.
