ABSTRACT:
The non-motorized aircraft flight control system provides additional lines, cords, hooks and other devices to existing paraglider aircraft to aid in the control of the paraglider wing elements such as the wing suspension lines which are used to change the shape of the wing to change the flight characteristics of the aircraft. The simplest version of the improvements facilitate the location and pulling of the appropriate control lines. Visual facilitators are used to aid in identifying the proper elements. The more complex changes involve cables and handle grips with gear systems similar to a bicycle shifting mechanism. In all cases where a control position is to be maintained for a period of time there is a device to retain the cord or cable in the proper position. A further variation involves the use of a transmission box to shift and control the cables and to use the pilot's leg to aid in manipulation of various elements of the paraglider. All of the elements do not have to be included on any given paraglider, but those controls desired by the pilot may be chosen such as the basic elements to retain the brake handles in the optimum position.
