Hello, when I create a flight plan and load it to the previous simulator such as fsx the route is exactly as I created it. However when I load it to the msfx in the simulator ive got other route. I didn’t understand why. Any help? Thank you Eran Granot ---

Hi Eran, its a sim limitation, that whenever you made any changes the sim makes a totally recalculation of the route. Has nothing todo with the underlying navdata (NavBlue or our from Jeppesen). Its the logic in the sim - we can’t do anything for this logic,sorry. Cheers Richard ---
