Hi!

As far as I understand, it's possible to get the F-16 into a deep stall (or inverted deep stall?). Will the engine get enough air without the "normal" airflow? Is the pilot supposed to move the throttle to idle ? And if he is, is that to prevent flameout? Or does that (idle), just make it easier to get out of the deep stall? Shocked

AFAIK, the only way to extricate oneself from a nasty thing like a deep stall is to rock out of it using the stick, rudder, and the MPO.

I believe the bold face is to come to idle so the DEEC can open the nozzle and maintain proper stall margins. But don't quote me. Wink

I don't ever recall the motor either having a compressor stall or a flameout when we did deep stall training in the sim. But then again that was an ideal engine model.

Actually, there are two different procedures depending on the engine, although you can experience an engine stall or stagnation in a deep stall, regardless of the engine type.

If you're flying a Pratt, you retard the throttle to MIL if you're in AB. If you're already at MIL or below, you don't touch the throttle until you've recovered.

With the GE motor, engine stalls are a concern, but engine siezure due to oil starvation at prolonged negative G's is a much bigger concern. Therefore, if you go out of controll, you retard the throttle to Idle and don't touch it until you've recovered

Thanks all for your quick replies. You guys really know a lot about the F-16!

What a great site this is! Laughing

Did not know you were to keep the throttle @ Mil Pwr if not in AB during spin recovery, excellent posts about spins in the F-16.

Engine flameout during deep stall ?
