What is the correct general guideline for night operations regarding aircraft lighting?

• A. All lights on when stationary
• B. All lights on when in motion
• C. Only nav lights during takeoff
• D. Strobes on only during approach

Answer: (B)

When you’re operating at night, visibility to others is the key safety factor. The best general guideline is to have all lights on whenever the aircraft is moving. This makes the aircraft highly conspicuous to other pilots and ground personnel, reducing the risk of collisions. Navigation lights show your orientation, anti-collision lights grab attention, and landing lights add brightness during critical phases, all helping others to see you sooner. Keeping lights off while stationary isn’t necessary and doesn’t improve safety, and limiting lighting to only某 during takeoff or only during approach would miss opportunities to be seen during other flight phases. So, the safest, most effective practice is to keep all lights on whenever the aircraft is in motion.
