INTRODUCTION Hydraulic power is provided by three independent systems designated No.1, No.2 and No.3. All systems operate at a nominal pressure of 3000 psi (20,685 kPa) and use synthetic hydraulic fluid “Skydrol”. WARNING Skydrol is highly corrosive and can produce severe skin and eye irritation. Systems 1 and 2 are serviced by ground service panels located in the aft equipment compartment. System 3 is serviced by a ground service panel located on the right side of the fuselage, aft of the wing root. Each system has two hydraulic pumps; a main pump (A) for normal power and a backup pump (B) for supplementary power. System No.1 and 2 main pumps are engine driven pumps (EDP’s). System 1 EDP (1A) is driven by the left engine and system 2 EDP (2A) is driven by the right engine. System 1 and 2 backup pumps (1B and 2B) are electrical AC motor pumps (ACMP’s). Both hydraulic pumps for system No.3 are ACMP’s. In system No.3, the main pump (3A) normally runs continuously, while the backup pump (3B) is available during periods of high flow requirements. The hydraulic systems supply power to operate the rudder, elevators, ailerons, spoilerons, flight spoilers, ground spoilers, wheel brakes, nosewheel steering and landing gear extension and retraction. The rudder, elevators and ailerons are powered by more than one hydraulic system to prevent loss of critical flight controls. During a total AC power failure in flight, pump 3B will be automatically powered by the air driven generator (ADG) when it is deployed. This will provide hydraulic pressure to the landing gear, brakes and nosewheel steering and also provides backup hydraulic pressure to the primary flight controls.
