What is the maximum altitude for a UAS operating under Part 107?

The maximum altitude for a Unmanned Aircraft System (UAS) operating under Part 107 is 400 feet above ground level (AGL). This regulation is in place to ensure safe operation and to minimize the risk of collisions with manned aircraft, which typically fly above this altitude. When flying near structures, a UAS may operate up to 400 feet above the top of the structure, provided that the operator remains within the defined 400-foot limit relative to the elevation of the ground below.

Operating at this altitude also helps to maintain safe airspace management and promote the integration of UAS operations into the national airspace system. Understanding this altitude limit is crucial for commercial drone pilots, as adherence to these regulations is necessary to maintain compliance and ensure safety in drone operations.
