Which indicator shows that one or more thrust reverser sleeves are not in the commanded state?

• A. An illuminated amber reverser light
• B. A white reverser status light
• C. A blinking amber indicator
• D. A green REV indication

Answer: (A)

When examining reverser indicators, you’re looking for a signal that the system has not matched the commanded sleeve position. An illuminated amber reverser light is the warning that one or more thrust reverser sleeves are not in the state that was commanded. Amber is used to denote caution or a fault condition, signaling a mismatch that requires attention. The other indicators don’t specifically denote this mismatch: a white reverser status light shows a reverser status but not necessarily a deviation from command; a blinking amber indicator generally points to a fault or advisory condition but isn’t as direct a signal of being out of the commanded state; a green REV indication means the reverser is in the commanded state and functioning normally, which is the opposite of the condition described.
