Except in Alaska, during what time period should lighted position lights be displayed on an aircraft?

1. Sunrise to sunset

2. 24 hours a day

3. Only at night

4. Only during takeoff and landing

The correct answer is: Sunrise to sunset

The correct answer is that lighted position lights on an aircraft should be displayed from sunrise to sunset, except in Alaska. This is based on regulations that require aircraft to exhibit certain lights to enhance visibility and safety during operation. Position lights help other pilots and ground personnel to identify the aircraft's position, heading, and status, especially during times of daylight when visibility may still be a concern, particularly in conditions like haze or overcast skies. While some might argue that the lights should be on 24 hours a day or only at night, this is not mandatory under standard regulations outside of Alaska. The rationale behind having the lights activated only from sunrise to sunset is to conserve energy and avoid unnecessary light emissions when they are least needed. The options referring to takeoff and landing periods also do not encompass the broader requirement for visibility during the daylight hours. Thus, displaying position lights from sunrise to sunset is aligned with safety protocols without excessive use during the brightest parts of the day.
