Abstract: An exemplary method for controlling low speed flight of an aircraft having a controller receiving pilot input includes transitioning from a translational rate command (TRC) to a linear acceleration command (LAC) when the controller is displaced above a control transition displacement (CTD), and while in LAC holding speed when the controller is relaxed to CTD.

Abstract: A rotorcraft comprising a rotor blade designed to flap about a hinge point, a measurement system designed to measure blade flapping, and a processing system designed to alter blade flapping measurements. The processing system further comprises a correction process to alter a blade flapping measurement dependent on rotor RPM or rotor torque.
