Abstract
In an example, a system includes a first controller for controlling a first-flight-control surface, a second controller for controlling a second-flight-control surface, and a first override system including a mechanical linkage between the first controller and the second controller. The first override system is configured such that: (i) while less than a first threshold amount of force is applied to the mechanical linkage, movement of the first controller causes a corresponding movement of the second controller and vice versa, and (ii) while greater than the first threshold amount of force is applied to the mechanical linkage, the first controller and the second controller move separately. The system also includes a second override system operable to permanently disconnect the mechanical linkage responsive to greater than a second threshold amount of force applied to the mechanical linkage. The second threshold amount of force is greater than the first threshold amount of force.
