What does a green REV indication above the N1 RPM readout mean?

• A. Thrust reverser is deployed
• B. Engine start switch FLT
• C. Ignition to both igniters
• D. Auto-restow circuit activated

Answer: (A)

A green REV indicator above the N1 RPM readout shows that the thrust reverser is deployed. The color green signals normal, active operation, so you know the reverser doors are open and redirecting engine thrust forward to help slow the aircraft on landing. This cue is separate from ignition or auto-restow systems, which would use different indicators. If the reverser were not deployed or there were a fault, this light would not be green (it would be off or show a fault indication), helping you confirm the reverser state at a glance.
