Left Hydraulic System Pressure

QRH Inoperative Items:

• Left Autopilot
• Left Thrust Reverser

PTU power may not be available if hydraulic fluid is lost. If the PTU is unavailable the following are inoperative Items:

• Automatic Speedbrakes

  The main gear trucks remain un-tilted during alternate gear extension, which is the final signal for the automatic speedbrake extension. If the speedbrakes were armed, alternate extension used and the thrust levers subsequently closed at some point during the approach, the speedbrakes would extend fully.

• Nosewheel Steering
  [Powered through the landing gear normal down lines.]
• Flaps and Slats hydraulic operation
• Landing Gear hydraulic operation

Notes:

• Do not use Autobrakes

  If nosewheel steering is inoperative, then differential braking will be required to keep the aircraft straight on the runway. The autobrake system can only provide straight-line braking and differential braking is not available during autobraking.

• Ensure Speedbrakes extend before using Right Thrust Reverser

  Thrust Reverse will cause a yawing action that must be countered using differential braking. Ensuring speedbrakes are deployed prior to thrust reverse will maximise weight on wheels, thus maximising differential braking.

• A SPOILERS EICAS message can be expected as not all panels will move.
