When are position lights required to be on during night flight?

Position lights are required to be on at all times during night flight to ensure visibility of the aircraft to other air traffic and ground vehicles. These lights help indicate the aircraft's orientation by showing its position in the airspace, and their constant use enhances flight safety by reducing the risk of mid-air collisions.

While there may be specific recommendations or practices regarding lighting during certain phases of flight, the regulation requires that position lights be illuminated continuously from sunset to sunrise. This requirement aims to maintain a standard operating practice that prevents any potential omissions that could compromise safety during night operations.
