An electro-magnetic landing gear up-lock includes at least one electro-magnet mounted to the aircraft structure positioned adjacent the landing gear trunion. When the at least one electro-magnet is energized, magnetically responsive material in the landing gear positioned adjacent to the electro-magnet is attracted to the electro-magnet with sufficient force to hold the landing gear in a retracted. De-energizing the electro-magnet causes the electro-magnet to release the landing gear to allow the landing gear to extend. |
