When is it permissible to fly a sUAS at night under Part 107?

Under Part 107 regulations, it is permissible to fly a small Unmanned Aircraft System (sUAS) at night only when the drone is equipped with appropriate anti-collision lighting. This requirement is in place to ensure that the pilot can maintain visual line of sight, as well as to ensure that other aircraft in the vicinity can see the drone. The lighting must be sufficient to make the sUAS conspicuous for other airspace users and must provide adequate illumination for the pilot to maintain control during night operations.

Flying at night without such lighting would compromise safety, increasing the risk of mid-air collisions and reducing the pilot's ability to operate the drone effectively. It's important to note that additional measures, such as training and operational planning, also contribute to the safety of night operations under Part 107.

Other options, while they may seem plausible, do not align with the regulatory framework set by the FAA. For example, having a visual observer may enhance situational awareness but is not a substitute for required lighting. Twilight hours, while a period of lower visibility, still necessitate the presence of anti-collision lights for night operations. Additionally, permission from local law enforcement doesn't substitute or alter the requirements of the FAA regulations concerning sUAS operations.
