Abstract
When a stall is detected during high power operation, the engine is given one chance to recover without a change in bleed schedule. Should a second stall occur within 10 seconds the control system switches to an override bleed schedule for 51/2 minutes, or until throttle is reduced. This supplies a minimum adaquate thrust for a limited time.
