Abstract: A controlling mechanism for a direct lift control system which is utilized primarily during the landing phase of aircraft flight to reduce the response time of the aircraft to longitudinal or pitch commands. The system incorporates modulated spoilers to affectuate augmented vertical control of the flight path of the aircraft without necessarily changing the pitch attitude thereof. When the aircraft is preparing to land and the flaps are placed at the desired landing flap angle, the mechanism raises the spoilers on each wing symmetrically to a predetermined bias position. The mechanism thereafter causes the spoilers to operate up and down from this bias position in response to elevator commands generated either manually by the pilot or automatically by the autopilot. The mechanism also includes means to disengage the system automatically during stalls, go-arounds, landing rollout, or manually whenever the pilot desires.

Abstract: A mechanical mixer for producing a spoiler controlling output by predeterminately combining lateral, speed brake, ground spoiler and direct lift control inputs. The mixer accomplishes this through the use of cams, followers, summing linkage, and override devices.

Abstract: A control wheel steering device for manually applying override changes in aircraft attitude during autopilot control. Electrical signals fed to a flight guidance computer are varied by pilot pressure on a spring which deflects and in turn modulates an electronic transducer.
