Tested a bit more. There seems to be an interaction with cold-start, try this:
- Start AeroflyFS in safe mode.
- Select the C172.
- Go to Lompoc Airport (LPC/KLPC)
- Choose the parking spot and a Cold Start.
- Start the scenario. No need to do anything.
- Go back to location and choose long approach to 07.
- Start the scenario and notice the throttle setting. It is at 2300 RPM. Flaps are down full, however, I was wrong when I wrote the report.
- Now go to the location menu again, and choose the same approach.
- When you start the scenario now, the throttle setting is properly at 1850 RPM, set for a descent for landing.
