QRH Inoperative Items:

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
  • Flaps and Slats hydraulic operation
  • Landing Gear hydraulic operation

Notes:

  • Crosswind limit is 20 knots
  • 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.

  • Use differential braking
