In-flight emergency situations
Engine surging
Excessive angles of attack during maneuvering, excessive throttle application or unpredictable
ingestions of foreign matter can cause interruption in the airflow and lead to the compressor stall with
following surging and possible backfire with a loud “bang”.
If it happens do the following:
1. Pull the throttle back to IDLE Numpad-.
2. Adjust attitude to some negative pitch and free fly at approximately 185 KIAS.
3. Smoothly push the throttle back to the desired position and continue the flight Numpad+.
Air start
If the engine is stalled in the air, you can try to bring it back to life:
1. Pull the throttle back to IDLE Numpad-.
2. Adjust attitude to add some negative pitch and fly at approximately 185 KIAS.
3. Check the RPM indicator. If the compressor auto-rotation speed is about 23–34 % press
R.Shift + Home to ignite the engine.
