Tactair Landing GearDoor Uplocks utilize a simple and robust mechanical latching design for retaining the Landing Gear in the 'Up' position. The latching design includes two methods of release for lowering the landing gear, a normal and alternate mode. In the normal mode, a hydraulic actuator is used to release the landing gear in the normal mode of operation. In the alternate mode, a manual release cable is used to actuate the mechanical release into the uplock.
