Title: SPLIT-AILERON CONTROL
Abstract:
The present disclosure provides methods and system for controlling the operation of an aircraft aileron which comprises an inboard portion and an outboard portion. A velocity of the aircraft is determined. Then, based on the velocity of the aircraft, the aileron is caused to move in certain ways. Below a first velocity threshold, the inboard aileron portion and the outboard aileron portion are caused to move substantially in unison. Between the first velocity threshold and a second, greater, velocity threshold, the outboard portion of the aileron is caused to lock and the inboard portion of the aileron is caused to move independently from the outboard portion. Above the second velocity threshold, the inboard portion is caused to move substantially opposite from the outboard portion.
