Abstract: A control system for controlling a tiltable wheel truck of a main landing gear includes an auxiliary strut, a ground mode system operably connected with the aircraft for detecting and providing signals indicative of when the aircraft is on the ground; a takeoff mode system operably connected with the aircraft for detecting and providing signals indicative of when the aircraft is operating in a throttled-up mode; and an auxiliary strut control unit operably connected with the ground mode system, takeoff mode system, and auxiliary strut. The auxiliary strut control unit is operable to issue a lock-up command signal to the auxiliary strut upon detecting signals from the systems indicating that the aircraft is on the ground and that the aircraft is operating in a throttled-up mode, whereby the auxiliary strut is caused to lock up during a takeoff roll but is unlocked during other operating modes of the aircraft.
