The RSVR light illuminates when either reservoir quantity and/or air pressure are low.


QRH 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.

  • Right and Centre Autopilots
  • Normal Brakes
  • Primary Source to Alternate Brakes
  • Autobrakes

    Autobrakes requires a full Antiskid system, but with the Alternate Brakes in use, Antiskid is only available to laterally paired wheels.

Notes:

Other minor inoperative systems:

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