20080234881 | VERTICAL SPEED AND FLIGHT PATH COMMAND ALGORITHM FOR DISPLACEMENT COLLECTIVE UTILIZING TACTILE CUEING AND TACTILE FEEDBACK - A flight control system includes a collective position command algorithm for a lift axis (collective pitch) which, in combination with an active collective system, provides a force feedback such that a pilot may seamlessly command vertical speed, flight path angle or directly change collective blade pitch. The collective position command algorithm utilizes displacement of the collective controller to command direct collective blade pitch change, while a constant force application to the collective controller within a “level flight” detent commands vertical velocity or flight path angle. The “level flight” detent provides a tactile cue for collective position to reference the aircraft level flight attitude without the pilot having to refer to the instruments and without excessive collective controller movement. | 09-25-2008 |
