Non-binary collaborative recovery system

Abstract

A processor supplies flight commands to the flight control system by selectively blending pilot input with control signals from the autopilot. The processor generates a projected recovery trajectory through successive iterations, each beginning at the current aircraft location and using a recovery constraint selectable by the processor to influences a degree of flight aggressiveness. A detection system that identifies and invokes a state of threat existence if a threat exists along the projected recovery trajectory. The processor during threat existence in a first iteration commands an initial soft recovery, with permitted blended pilot input. If the threat exists on subsequent iteration, the processor commands a more aggressive recovery while attenuating blended pilot input.

Description

[0001] priority claim [0002] Pursuant to 35 U.S.C. §229(e), this application claims priority to U.S. Provisional Application No. 62 / 723,187, filed August 27, 2018, entitled "AircraftFlight Envelope Protection Framework," the entire disclosure, drawings, and appendices Included herein by reference. technical field [0003] The present disclosure relates generally to aircraft flight envelope protection systems, and more particularly to aircraft flight envelope protection systems that model potential aircraft trajectories and test those trajectories for aircraft restriction violations and terrain avoidance hazards. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Aircraft are designed to operate within certain operating speeds and loads with respect to the control surfaces of the aircraft. These operating limits are known as the flight envelope, outside of which it is po...

This might work for a military aircraft, with the pilot wearing a helmet, strapped into the ejection seat system, ready to absorb the hard recovery g-forces, but not for a commercial or commercial aircraft
