What type of lights should be flashed for fixed wing aircraft during sunset to sunrise?

The correct answer is that navigation and landing lights should be used for fixed-wing aircraft during the hours of sunset to sunrise. Navigation lights are essential for indicating the aircraft's position and direction to other aircraft and are typically found on the wingtips, at the tail, and on the nose of the aircraft. These lights help to enhance visibility and situational awareness during the night or in low-light conditions.

Landing lights are crucial as they provide increased illumination of the runway and its environment when an aircraft is approaching for landing. These lights can be turned on when an aircraft is on final approach or during taxiing in low-visibility conditions, thereby becoming doubly important during the night when depth perception can be affected.

The other options do not correctly address the specific requirements for visibility and safety during nighttime operations. For instance, while strobe and beacon lights are also used on aircraft and add to visibility, they are not primarily used for navigation and landing purposes, making the chosen answer the most applicable in this context.
