Changing the aircraft.cfg worked! In the picture below I have the MILVIZ Pilatus PC6 Amphibian I am flying, and two MILVIZ DHC2 tail draggers with Tundra wheels which I inserted with AI schedules. They both taxied and took off from Misty's Place PF20. Now they still taxied through buildings and one bounced off a mountain after take off, but that's progress.
Question... with the aircraft.cfg changes... will it make flying those payware models a problem?
For those interested, I am using AI Flight Planner AIFP to create the AI flight plans and BGL files.
