What is the maximum altitude a UAS can be flown without special authority?

The maximum altitude a UAS (Unmanned Aircraft System) can be flown without special authority is 400 feet above ground level. This regulation is outlined by the Federal Aviation Administration (FAA) to ensure safety and maintain an orderly separation between manned aircraft and unmanned systems.

Flying at or below this altitude helps minimize the risk of potential collisions with manned aircraft, which typically operate at higher altitudes. It also provides UAS operators with a clear and defined regulation that can be easily understood and followed.

By keeping the flight altitude at 400 feet or below, operators can conduct their operations within the established safety guidelines, allowing for a productive use of airspace without special permissions or waivers. Certain types of operations, such as flying in restricted or controlled airspace, may require additional authority, but within the established limits, operators can safely manage their flights.
