What is the required use of anti-collision lights during night flight?

During night flight, anti-collision lights are required to be used at all times. This requirement ensures that the aircraft is visible to other pilots and ground personnel, reducing the risk of mid-air collisions and increasing safety. The use of these lights contributes to the overall situational awareness of both the pilot and other aircraft in the vicinity, especially during the dark, when visibility is limited.

By keeping anti-collision lights on throughout the duration of the night flight, pilots can help to ensure their aircraft remains conspicuous against the night sky, thereby promoting safety both in the air and on the ground. This practice aligns with the regulations set forth by aviation authorities, which focus on minimizing risks associated with reduced visibility conditions during nighttime operations.
