Verified from official sourcesAC 91-57C ¶ 3.4.4Version 2Effective -Verified 29 August 2026
In plain language
If you fly at an FAA-authorized fixed site in controlled airspace (Class B, C, D, or surface Class E), you do not need to apply for individual airspace authorization (like LAANC), provided you follow the site's agreed ATC operating procedures.
Requirement as structured
Recreational flyers may operate small UA or UA over 55 pounds at FAA-authorized fixed sites in Class B, C, D, or surface Class E airspace without obtaining individual airspace authorizations, provided they comply with the ATC operating procedure.
Original regulatory text
3.4.4 A CBO does not have to request the establishment of a fixed site as part of the CBO recognition process. However, a CBO may submit a request to the FAA for the authorization of a fixed site. When a fixed site has received FAA authorization, 10/20/22 AC 91-57C 3-9 recreational flyers will be able to use the site to conduct recreational operations using small UA or UA more than 55 pounds, or participate in a CBO-sanctioned event in such controlled airspace (i.e., Class B, C, or D airspace or within the lateral boundaries of the surface area of Class E airspace designated for an airport), without additional airspace authorizations. These operations are subject to the parameters of a mutually agreed upon operating procedure with the ATC facility. Interested parties may request authorization for a fixed flying site by submitting their request through the FAADroneZone website at https://faadronezone.faa.gov/. Any request submitted to the FAA for the authorization of a fixed site should include the following information: 1. Latitudes and longitudes that define the boundaries of the proposed site. Text, picture, and geographic files are generally acceptable file formats for depicting the requested area. 2. Maximum altitudes requested for operations at the site. 3. Hours of operation at the site. 4. Description of any unique operations, if applicable, including: • Large (more than 55 pounds) UA operations. • Turbine engine operations. • Combat simulations. • Racing operations. • Aerobatics. 5. Airspace classification. 6. Nearest airport. 7. Photos of site location. 8. Previous Letter of Agreement or Authorization, as applicable.
