Abstract: A slat and modulatable flap control system for an aircraft having slats in the leading edge of the wing and having flaps in the trailing edge of the wing. A detent pin on a control handle, and any one of four detent slots on a detent crank, can be engaged to selectively, and automatically, set the flaps and the slats (because of the cooperative action of other constituent components of the control system) in optimum positional relationship for takeoff/"go-around," cruising, approach, and landing of aircraft. The control system is ideally suited for aircraft used in "short takeoff-and-landing" situations.

Abstract: A selectable dual ratio connection between the rudder pedals and the control elements of an aircraft for steering the aircraft by means of the nose mounted landing gear wheel thereof. The connection includes a control arm and a control segment selectively related either by a link, walking beam and bungee or by means of a pivoting link mechanism. The arm and segment are rotatably mounted upon axes that coincide with the pivoting link mechanism which in one position locks the arm and the segment together while in another position enables differential motion therebetween.
