What is the maximum altitude a UAS can fly according to Part 107 regulations?

According to Part 107 regulations established by the FAA for the operation of small Unmanned Aircraft Systems (UAS), the maximum altitude that these drones can fly is 400 feet above ground level (AGL). This regulation is in place to ensure safe operations and to minimize the risk of collisions with manned aircraft, which typically operate at higher altitudes. The 400-foot limit helps maintain a clear separation between UAS operations and general aviation traffic.

This altitude restriction applies to all UAS operations in uncontrolled airspace. Additionally, if a UAS is flown above 400 feet, it needs to maintain its altitude in relation to nearby structures, meaning if a drone is operating near a building or other tall structure, it can fly up to 400 feet above the highest point of that structure. This ensures a clear and consistent operational framework for drone pilots, contributing to the safety and effectiveness of airspace management.

The other options propose altitudes that exceed the maximum allowed limit specified by Part 107, making them non-compliant with the regulations governing safe UAS operations.
