A hydraulic system for aircraft operating devices provides a secondary pressure source for direction and deceleration control in case of loss of pressure from a primary pressure source. The system includes multiple pressure accumulators that include a primary accumulator, which supplies pressurized fluid to a first actuator, and first and second secondary accumulators, which supply pressurized fluid to second and third actuators, respectively. If the primary accumulator is disabled, the first secondary accumulator will supply pressurized fluid to the first actuator. If the first secondary accumulator is disabled, the second secondary accumulator will supply pressurized fluid to the second actuator. By providing multiple, substantially independent accumulators, direction and deceleration control is maintained even in the event of loss of the primary accumulator.

What is claimed is: 1. A hydraulic system for aircraft operating devices comprising:a plurality of hydraulic actuators for respective aircraft operating devices, including at least one first actuator and at least one second actuator, anda plurality of hydraulic pressure accumulators, includinga primary accumulator connected to the at least one first actuator, anda first secondary accumulator that receives pressurized fluid from the primary accumulator and which is normally connected to the at least one second actuator;and wherein, upon loss of operating pressure from said primary accumulator, said first secondary accumulator is connected to the at least one first actuator.
