What is the maximum altitude a Remote Pilot can fly a UAS without a waiver?

The maximum altitude at which a Remote Pilot can operate a UAS without a waiver is 400 feet above ground level (AGL). This regulation is set forth by the Federal Aviation Administration (FAA) to ensure safe integration of unmanned aircraft systems into the national airspace.

Flying at or below this altitude helps to minimize the risk of collisions with manned aircraft, which typically operate at higher altitudes. Additionally, it ensures that UAS operators maintain visual line of sight with their aircraft, a critical safety practice. In controlled airspace, drone operators must follow additional regulations, but the 400-foot altitude limit serves as a fundamental guideline for operations in both uncontrolled and controlled environments.
