When the landing gear is down, in which scenario will the green light not illuminate?

• A. If wire number 6 is shorted
• B. If wire number 6 is open
• C. If any wire is disconnected
• D. If the landing gear is malfunctioning

Answer: (B)

In the scenario where the landing gear is down, the green light indicating that the landing gear is in the correct position will not illuminate if wire number 6 is open. An open wire means there is a break in the circuit, preventing electrical current from flowing. Since the green light is dependent on the completion of the electrical circuit that checks the status of the landing gear, an open circuit caused by wire number 6 being cut or disconnected will fail to send the signal needed to illuminate the green light. In contrast, if wire number 6 is shorted, it may inadvertently cause the light to remain illuminated or produce an erratic function. Similarly, if any wire is disconnected, the system may still have enough alternate paths for power, depending on the specific design and redundancy of the circuit. If the landing gear itself is malfunctioning, the green light could still potentially illuminate if the circuit is intact; it would simply not reflect the actual status of the landing gear. Understanding electrical circuits and connectivity is crucial for diagnosing issues in avionics systems, which emphasizes the importance of the status of wire number 6 in this scenario.
