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 5½minutes, or until throttle is reduced. This supplies a minimum adaquate thrust for a limited time.

The method of obtaining acceptable thrust for a limited time from a gas turbine engine damaged by a foreign object comprising: continuously monitoring for the presence of a stall condition whenever the bleed valves are substantially closed; determining the presence of a stall condition; determining a subsequent recovery from the stall condition; monitoring for a second stall within a predetermined time of the recovery; continuing normal unrestricted operation if a second stall does not occur within the predetermined time; and opening bleed valves to a predetermined emergency schedule if a second stall occurs within said predetermined time.
