Patent attributes
A system and related methods for providing stall recovery guidance symbology via a head-up display (HUD) or similar avionics display element detects stall or near-stall conditions and provides symbology to guide the pilot through recovering from the stall by prioritizing pitch correction and disengagement of the autopilot system. Pitch correction symbology guides the pilot toward reducing the aircraft angle of attack and establishing level flight, while thrust recovery symbology helps the pilot control the application of thrust to avoid prolonging or reinstituting the stall. The system modifies the stall recovery symbology in response to detected changes in pitch, angle of attack, or airspeed. Once level flight has been established and stall conditions are no longer present, the system may transition out of stall recovery mode to regular inflight symbology.
