What is the maximum altitude a pilot can operate an RPA above ground level?

Pilots operating a Remote Piloted Aircraft (RPA) are allowed to fly at a maximum altitude of 400 feet above ground level. This regulation is in place to ensure safety and to reduce the risk of collisions with manned aircraft, which typically operate at higher altitudes. Staying below 400 feet helps maintain a clear separation from these aircraft and allows for better visibility and control of the RPA.

This limit is standardized by the Federal Aviation Administration (FAA) in the United States and is widely recognized in other regulatory environments as well, underscoring its importance in ensuring safe drone operations. Operating above this altitude can create significant safety hazards and is typically subject to more stringent regulations and air traffic control requirements.
