What is required to operate a small unmanned aircraft within 30 minutes after sunset?

To operate a small unmanned aircraft within 30 minutes after sunset, the use of anti-collision lights is mandatory. This requirement is aimed at enhancing visibility and safety during night operations, as well as ensuring that the aircraft can be seen by other airspace users. The lights must be visible for at least three statute miles, which helps prevent potential collisions and assists in maintaining situational awareness.

While other options might seem relevant in different contexts, they do not align with the specific regulatory requirement set by the FAA for nighttime operations. For example, special night vision goggles are not a standard requirement for UAV pilots, and flight training certification or notifying local authorities are not stipulated as necessary for night flying with small unmanned aircraft under current regulations. The primary focus for safely flying at night is ensuring that anti-collision lights are utilized to indicate the aircraft's presence in the airspace.
