QRH Inoperative Items:
  • Centre Autopilot
  • Right Autopilot Stabilizer Trim

    As the Right autopilot uses the centre Stabiliser Trim motor, the Right autopilot can only be used at the speed the stabiliser is trimmed for, and cannot be engaged at any other speed.

  • 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.

Notes:

Other minor inoperative systems:

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