What action should a recreational pilot take when planning to fly during twilight?

When planning to fly during twilight, confirming that visibility is at least 3 statute miles is crucial for a recreational pilot. This is because twilight, characterized by the time just before sunrise or just after sunset, presents challenges to visibility due to the diminishing natural light. Under such conditions, it's essential for pilots to ensure that they have sufficient visibility to navigate safely and avoid obstacles. The minimum visibility requirement helps ensure that pilots can see and avoid other aircraft, terrain, and any potential hazards in their flight path.

Maintaining adequate visibility is particularly critical during twilight, as the contrast between the sky and the ground may become challenging, potentially affecting a pilot's ability to judge altitudes and distances accurately. Therefore, ensuring visibility is a fundamental part of safe flight planning during these times.

The other options do not prioritize this aspect of safety. While filing a flight plan can be helpful in some contexts and booking a flight instructor for a briefing may provide valuable insights, these actions do not directly address the primary safety concern of ensuring visibility during twilight hours. Similarly, ensuring daylight hours have fully passed is not practical for twilight flying, as it could lead to missing the opportunity to fly during that specific period when conditions may still be favorable.
