Claim:
1. An air vehicle comprising: a fuselage; a pair of control surfaces movable relative to the fuselage; an actuator having a movable actuator shaft; and a coupler that selectively mechanically couples the actuator shaft to the control surfaces, wherein the coupler is in a disengaged condition when the actuator shaft and the control surfaces are not coupled by the coupler, and wherein the coupler is in an engaged condition when the actuator shaft and the control surfaces are coupled by the coupler; wherein the coupler is able to shift between the disengaged condition in which the control surfaces move independently of the actuator shaft such that movement of the actuator shaft does not cause movement of the control surfaces, and between the engaged condition in which the actuator shaft and the control surfaces are mechanically coupled such that movement of the actuator shaft causes movement of the control surfaces.
