[Option – RR engines]
• the reverser indication REV is displayed in amber above each digital TPR
indication (REV is displayed in amber when the reverser is in transit)
When the interlock releases:
• the reverse thrust levers can be raised to the maximum reverse thrust
position
• the REV indication changes to green when the reverser is fully deployed.
Pushing the reverse thrust levers to the full down position retracts the reversers to
the stowed and locked position. The thrust levers cannot be moved forward until
the reverse thrust levers are fully down.
The EICAS advisory message ENG REV LIMITED (L or R) is displayed if the
reverser cannot deploy when commanded, or can deploy only with reverse thrust
limited to idle. Not all conditions limiting or preventing reverse thrust can be
detected before reverse thrust selection. For these conditions, the reverse thrust
levers cannot be moved beyond the interlock position.
The EICAS advisory message ENG REVERSER (L or R) is displayed on the
ground to indicate a reverser system fault.
The EICAS caution message ENG REV AIR/GND is displayed when the
air/ground logic that prevents in-flight thrust reverser deployment has failed.
The EICAS caution message ENG REV COMMANDED (L or R) is displayed
when the left or right reverse thrust lever is not in the down position in flight.
