Aircraft spoiler lockout

Abstract:

Systems and methods are provided for aircraft spoiler lockout. One embodiment is a system that includes a locking device that removably engages a control member inside a cockpit of an aircraft. The locking device restricts motion of the control member to prevent movement of wing surfaces of the aircraft. The system further includes a controller in communication with a wireless transmitter. The controller determines from a signal sent by the wireless transmitter whether both handheld switches connected to the wireless transmitter are being actively held. If so, the controller directs a supply of power to the locking device thereby causing the locking device to temporarily release the control member. Otherwise, the locking device restricts motion of the control member.
