This lateral control system incorporates a load-feel bungee, which serves a dual purpose. First, it provides an artificial feeling and centering device for the aileron system. Also, it is an interconnection between the aileron system and the aileron trim system. When the aileron trim actuator is energized, the bungee moves in a corresponding direction and actuates the power mechanism. The power mechanism repositions the aileron control system to a new neutral position.
Some aircraft use a flaperon system.
The flaperon, shown in figure 1-5, is a device designed to reduce lift on the wing whenever it is extended into the airstream. With this system, control stick movement will cause the left or right flaperon to rise into the airstream and the opposite flaperon to remain flush with the wing surface. This causes a decrease of lift on the wing with the flaperon extended and results in a roll. The ailerons are located on the trailing edge of the outer wing panel and, unlike most aircraft, can be fully cycled with the wings folded. The spoiler extends upward into the airstream, disrupts the airflow, and causes decreased lift on that wing.
