What is the maximum altitude a Remote Pilot can fly a UAS under Part 107?

The maximum altitude a Remote Pilot can fly a UAS under Part 107 regulations is 400 feet above ground level (AGL). This limit is established to ensure that unmanned aircraft operate safely within the national airspace and to prevent potential conflicts with manned aircraft which typically operate at higher altitudes.

Flying at or below this altitude also allows remote pilots to maintain visual line of sight with their aircraft, which is vital for ensuring safe operations. The regulation takes into account both the safety of the UAS operations and the efficient management of airspace. Thus, operating at 400 feet AGL ensures the UAS is held at an adequate height while still allowing for the safe integration and operation among other airspace users.
