Under what circumstances is night flying permitted for drones?

Night flying for drones is permitted when the drone is equipped with anti-collision lighting. This is essential because anti-collision lights enhance the visibility of the drone in low-light conditions, making it easier for other pilots (including those of manned aircraft) and observers on the ground to see the drone and avoid potential collisions. The Federal Aviation Administration (FAA) regulations require that any unmanned aircraft system (UAS) operated at night must have lights that can be easily seen and that indicate the position of the drone.

While equipping a drone with GPS, holding a special night operation license, or limiting flights to urban areas may offer some advantages or meet certain criteria, they do not inherently address the safety concern of visibility during night operations. Thus, while the other options may contribute to the overall safety of drone operations, the specific requirement for night flying centers on having appropriate lighting to ensure visibility and safety.
