Thanks Dave, you were right about the version issue, I simply deleted P2A as a good measure and reinstalled it with the navdatapro 1706.
I am still getting x-plane 11 to crash during the flight after I had the airac message upon saving the flight plan from P2A to x-plane
I created the exact same flight plan right in the aircraft FMC waypoint after waypoints and could complete the whole flight without any crash!
i’m wondering What’s going on.
