One question I have, I'm not a real pilot, but I encounter many times that after a extreme recovery maneuver, mostly after dive bombing, the engine starts losing and recovery RPM, it does not goes to 0 RPM, it keeps increasing/decreasing RPM, I lost all speed and must Eject, cause I cannot relight the engine, after all is not stopped, it simply keeps doing that strange thing. Is that a compressor stall? How can I recover from it?
