What indicates the landing gear is down and locked on the indicator lights under typical conditions?

• A. No lights illuminated
• B. Three green lights
• C. Two green lights
• D. Three red lights

Answer: (B)

Indicator lights are there to show the status of each landing gear leg. Green means that a leg is down and locked. Seeing all three greens means every gear leg is extended and locked, giving you a clear, positive confirmation that the gear is ready for landing. If any light were red or off, that would indicate a problem or that a leg isn’t properly deployed or locked, so you wouldn’t have the full three-green signal. No lights visible wouldn’t indicate a confirmed down-and-locked state, so it wouldn’t be trusted as the proper condition for landing.
