When are navigation lights required to be operational on an aircraft?

• A. During takeoff
• B. At night
• C. In foggy conditions
• D. While taxiing

Answer: (B)

Navigation lights are required to be operational on an aircraft during night operations. The purpose of these lights is to ensure that the aircraft is visible to others in the airspace, allowing for better situational awareness and enhancing safety during low visibility conditions. When flying at night, the risk of mid-air collisions increases significantly, so it's vital that navigation lights are functioning to signal an aircraft’s position and direction to other pilots. While navigation lights might be useful in foggy conditions, they are not specifically mandated solely for that scenario. Similarly, lights are not a requirement during takeoff or while taxiing in the same capacity as during nighttime; they serve a different role during those phases of flight. Thus, the operational requirement during night flight is fundamental to aviation safety regulations.
