초록

A velocity command system is provided with a velocity stabilization mode wherein aircraft flight path referenced velocities are determined with respect to an inertial frame of reference, the flight path referenced velocities are held constant during pilot commanded yaw maneuvers so that the aircraft maintains a fixed inertial referenced flight path regardless of the pointing direction of the aircraft. Velocity control with respect to an inertial frame of reference is accomplished by controlling the aircraft flight path based on aircraft body referenced c...

청구항

An aircraft flight control system for providing control surface command signals to the aircraft control surfaces thereby controlling the yaw, pitch, roll and lift attitude axes of the aircraft in flight, comprising: velocity stabilization means for providing a velocity stabilization signal in response to the activation of a velocity stabilization mode; and velocity command means responsive to the presence of said velocity stabilization signal for maintaining a constant aircraft velocity with respect to an inertial reference.
