The 777 airplane has three independent Hydraulic Systems: left, right and center. The Hydraulic System power:
  • Flight Controls
  • Landing Gear
  • Leading edge slats
  • Nose and main wheel steering
  • Thrust reversers
  • Trailing edge flaps
  • Wheel Bakes
Flight control system components are distributed so that any one Hydraulic Sysytem can provide adequate airplane controllability. A Ram Air Turbine (RAT) provides backup Hydraulic pressure for some flight controls.
