[FIXED INTENALLY] P47 flies indefinitely with no engine and can even accelerate

icuham · December 22, 2020

First report:

Steps to reproduce:

1. Start in flying P47

2. Push RPM lever to full forward

3. Push Throttle Full forward (note that this disagrees with the link above)

4. Push boost full forward

5. Press the RPM increase switch full forward and do not let go until the engine fails

6. At this point the flight model will fail... but how it fails may be different with each successive test and may depend on the position of RPM control lever (the further forward it was at failure or after failure the more speed the plane will accumulate)

The flight model will fail with different modes:

plane could experience a down pitch attitude, up pitch attitude, typically hard right yaw, possibly roll in either direction. Pilot may blackout, or not, plane may be controllable or not. What is certain is that it will not stall or lose airspeed if the steps reflect our experience.

Tracks to be added.

track111158 is a view from one normal plane watching a plane with the bug, 110951 and 110656 are various tests. (More work TBD here... placeholders)
