Which of the following is a requirement for flying a UAS at night under Part 107?

To operate a UAS at night under Part 107 regulations, one of the key requirements is that the UAS must be equipped with anti-collision lights. These lights are crucial as they enhance the visibility of the drone to other pilots and personnel in the airspace, improving overall safety during nighttime operations. The requirement for anti-collision lights is designed to ensure that the drone can be seen from a distance and helps to prevent potential collisions with other aircraft and obstacles.

While other options may seem relevant, the regulation specifically mandates the use of anti-collision lights for night operation to enhance situational awareness and safety. Hence, this requirement is pivotal for maintaining safe operations during nighttime flights.
