In the context of solo flying, why is landing before sunset essential?

Landing before sunset is essential primarily to ensure proper visibility during landings. As the sun sets, the amount of available light diminishes, which can significantly affect a pilot's ability to see the runway, any potential obstacles, and other aircraft. Adequate visibility is crucial for successful landings, particularly for a solo pilot who may have less experience.

Good visibility allows for better judgment of distances, orientation, and overall situational awareness. Flying in twilight conditions or after dark can lead to misjudgment and increased risk due to reduced depth perception and difficulty in spotting terrain or other hazards. Therefore, planning to land before sunset helps maintain a high level of safety during solo flying operations.
