Abstract
A method for controlling an aircraft engine using a control system enables an engine to be operated at low power while hail is ingested. The control system includes a processor coupled to the aircraft engine. The method comprises receiving a plurality of sensed inputs from the aircraft engine, receiving current engine environmental operating conditions, determining a reference value for a controlled variable from a fuel flow schedule, generating a fuel-air-ratio for the reference value based on current engine environmental operating conditions, and enriching combustor fuel staging in response to the fuel-air-ratio.
