When is a UAS pilot required to notify air traffic control?

A UAS pilot is required to notify air traffic control when operating in controlled airspace because this type of airspace is regulated and requires coordination with ATC to ensure safety and compliance with aviation regulations. Controlled airspace typically includes airspace surrounding airports and certain high-traffic areas where manned aircraft operations are concentrated.

By notifying ATC, the UAS pilot can receive real-time information regarding other aircraft in the vicinity, any restrictions, and updates on air traffic flows. This communication is essential for avoiding conflicts and ensuring the safe integration of UAS operations with manned aircraft.

Other scenarios, such as emergency landings, operating in rural areas, or flying above a certain altitude, do not automatically require notification to ATC unless those specific conditions involve controlled airspace or present potential hazards to other aircraft.
