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

To operate a small unmanned aircraft during the 30 minutes after sunset, it is mandatory to use anti-collision lights. The requirement for anti-collision lights is in place to enhance the visibility of the drone to other aircraft and people in the vicinity, helping to reduce the risk of accidents. These lights are designed to be visible from a distance and assist in ensuring that the unmanned aircraft can be seen in lower light conditions, which is crucial for safe operation during twilight hours.

Visual aids, while potentially useful for a pilot's situational awareness, do not fulfill the requirement set by the FAA for nighttime operations. Ground support is important for many aspects of flight operations but is not specifically required for safety during night flights. Special training certifications are not explicitly necessary for nighttime operations under the existing regulations, though having the requisite knowledge and skills through appropriate training is always beneficial for safe and effective drone operation.
