This invention provides a flare control modification for pilot-in-the-loop aircraft maneuver command electronic flight control systems. During flare, pilot pitch control inputs are interpreted as incremental pitch attitude commands. The flare control modification allows conventional piloting technique (i.e., pitch controller pull-and-hold) to be used during flare, while retaining the benefits of maneuver command system masking effects of gusts, winds, wind shear, and variations in airplane weight, balance, and aerodynamic configuration.


1. In an aircraft maneuver command electronic flight control system wherein during up-and-away flight a continuing pitch axis control signal is produced by a continuing steady input applied to a pilot-operated pitch axis control device, the improvement comprising a flare mode modification that becomes active during the flare portion of a landing, said flare mode modification including command modification means responsively connected to said pilot-operated pitch axis control device for receiving said pitch axis control signal and producing an incremental...
