Abstract
An aircraft-based stall prediction and recovery system may be embodied in a flight control system connected to aural/visual annunciators and flight controls (e.g., throttles and control surfaces). Based on received environmental data, the stall prediction and recovery system may detect imminent upset conditions (e.g., underspeed or overspeed) based on minimum and maximum operating speeds for the current airframe, altitude, and atmospheric conditions. The stall prediction and recovery system may notify the crew of the imminent upset and advise corrective measures. If a stall warning is received, the stall prediction and recovery system may engage an auto-recovery mode, notifying the crew of the engagement and restoring the aircraft to a safe target airspeed via automated recovery procedures, e.g., correcting the aircraft angle of attack and/or attitude. Upon resolution of the stall, the stall prediction and recovery system may disengage the auto-recovery mode, notifying the crew via the annunciators.
