If you start a flight with a Flight Plan (i.e. make one from the map page) and then delete it, it’ll spring back into the G1000 as soon as you hit the first waypoint.
Repro steps:
- Start new flight from one airport to another
- Once in the aircraft, use the G1000 to delete the flight plan (it successfully deletes)
- Use the G1000 to make a new flight plan
- Use the AP NAV mode to fly to the first navaid on the new FP
- Once you get to the first navaid, the new flight plan will disappear completely and you’ll be back on step one of the original one
