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

The maximum altitude for flying a UAS (Unmanned Aircraft System) under Part 107 regulations is set at 400 feet above ground level (AGL). This regulation is in place to ensure safe integration of UAS into the national airspace while minimizing the risk of mid-air collisions with other aircraft, particularly manned aircraft, which generally fly above this altitude.

When operating within certain parameters, such as if the UAS is within a 400-foot radius of a structure, the altitude can be extended to 400 feet above the structure, allowing for flexibility based on operational needs. However, the general limit remains at 400 feet AGL regardless of the conditions.

Understanding this altitude limit is critical for UAS operators to ensure compliance with aviation regulations and to maintain safety during operations.
