The Federal Aviation Administration (FAA) is the U.S. federal agency responsible for regulating civil aviation to ensure safety across the U.S. National Airspace System.
Aircraft Registration: Any RC plane, glider, or drone weighing between 0.55 lbs (250g) and 55 lbs (25kg) must be registered with the FAA via FAADroneZone. The registration number must be displayed on the exterior of the aircraft.
TRUST Knowledge Test: Recreational pilots must pass The Recreational UAS Safety Test (TRUST), a free online safety and rules exam, and carry proof of completion when flying.
Remote ID Compliance: Unless flying at an FAA-Recognized Identification Area (FRIA)—such as many AMA chartered club fields—RC aircraft must broadcast location and altitude data via built-in or module-based Remote ID hardware.
Operational Limits: Pilots must keep aircraft below 400 feet above ground level in uncontrolled airspace, maintain a visual line of sight at all times, and yield right-of-way to crewed aircraft.
Airspace Authorization: Flying in controlled airspace (near airports) requires prior authorization through automated tools like LAANC (Low Altitude Authorization and Notification Capability).
