AIM ¶ 11-4-1 — Recreational UAS Operations
AIM 11-4-1 explains recreational UAS rules: 400 ft AGL limit in Class G, CBO safety guidelines, LAANC, and authorizations for controlled airspace.
AIM 11-4-1 explains how recreational drone flyers can operate legally under the statutory exception in 49 USC 44809. If you don't follow every condition of the exception, the FAA treats your flight as a 14 CFR Part 107 operation — which can mean bigger penalties for unsafe flying.
Key operating limits:
- Class G airspace: Maximum altitude is 400 feet AGL. You must follow safety guidelines from a recognized Community-Based Organization (CBO).
- Class B, C, D, or surface E airspace: Prior FAA authorization is required before flight.
- Class G above 400 feet AGL: Also requires prior authorization.
Two routes exist for accessing controlled airspace:
- Fixed Sites — FAA-authorized locations shown as blue circles on the UAS Data Delivery System (UDDS) map, with altitudes derived from the UASFM.
- LAANC — the Low Altitude Authorization and Notification Capability provides near-real-time access at or below posted UASFM altitudes.
CBO sanctioned/sponsored events in controlled airspace must be coordinated with the FAA via DroneZone. Class G events at or below 400 ft AGL need no FAA approval, but events that may exceed 400 ft AGL do.
This paragraph is informational guidance, pointing to AC 91-57, 49 USC 44809, and 14 CFR Part 107 for the actual rules.
