Abstract

The left and right main landing gears on an aircraft are normally controlled by separate hydraulic power packs (HPP). Each HPP (110A, 110B) is sized for the load of the respective main landing gear actuator (102, 104). During failure of one of the HPP, a backup valve arrangement (140) actuates to allow the other HPP to operate both main landing gears. With the backup valve arrangement actuated, the pump (120) of the functioning HPP is coupled to the reservoirs (118) and to the load interfaces (112) of both HPPs, to actuate both main landing gear actuators.
