Which statement is true regarding the REV icon on the EICAS and forward thrust?

• A. The REV icon amber or green indicates it is safe to advance thrust levers
• B. The REV icon must be red to advance
• C. The REV icon color is not related to thrust advancement
• D. You can advance thrust before any REV icon appears

Answer: (A)

The REV indicator on the EICAS shows the reverser system’s readiness before you move the engines into forward thrust. When the reversers are safely stowed and the system is ready, the indicator will display amber or green, meaning it’s safe to advance the thrust levers. If the reverser condition isn’t safe, the indicator would be red or not in a safe color, and you should not advance. This color cue is what tells you you have cleared the reverser system checks and can smoothly transition to forward thrust, which is why amber or green is the best signal to proceed. Advancing thrust before any REV indication appears isn’t appropriate because you wouldn’t have a visible, confirmed safe state of the reversers.
