In the landing gear down condition, the green light will not come on if an open occurs in wire _______.

• A. No. 2
• B. No. 4
• C. No. 6
• D. No. 5

Answer: (C)

The green landing-gear light is powered only when there is a complete electrical path for that indicator in the gear-down condition. In this setup, current must flow from the power source through the gear-down circuit and then through the wire that carries the signal to the green lamp and finally to ground. If that essential wire opens, the circuit is broken and no current reaches the green light, so it will not illuminate even though the gear is down. The other wires may be involved in feeding other indicators or other parts of the system, but they don’t form the necessary path for the green light in this condition, so their opens wouldn’t prevent the green light from coming on.
