What communication is required when operating a UAS near an airport?

When operating a UAS near an airport, requesting authorization from Air Traffic Control (ATC) is a requirement to ensure the safety and efficiency of airspace operations. This is particularly important because UAS can present safety risks to manned aircraft, especially in controlled airspace where ATC manages the flow of air traffic.

By seeking authorization, the UAS operator informs ATC of the intended operation, allowing them to consider the UAS in their traffic management and issue necessary instructions to prevent potential conflicts with manned aircraft. Compliance with this requirement also signifies adherence to the regulations set forth by the FAA, which are designed to maintain safe operations in the vicinity of airports, especially in Class B, C, and D airspace.

In contrast, the other options lack the necessary compliance with regulatory standards for operating in proximity to airports. Not communicating or only notifying the airport does not suffice in ensuring that all air traffic remains safe and coordinated.
