FAA Order JO 7400.11K, Airspace Designations and Reporting Points, dated August 4, 2025, which lists Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points, was approved for incorporation by reference (IBR) by the Director of the Federal Register in accordance with 5U.S.C. 552 (a) and 1 CFR part 51. The approval to incorporate FAA Order JO 7400.11K by reference is effective September 15, 2025, through September 15, 2026. During the incorporation by reference period, proposed changes to the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points will be published in full text as proposed rule documents in the Federal Register, unless there is good cause to forego notice and comment. Amendments to the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points will be published in full text as final rules in the Federal Register. Periodically, the final rule amendments will be integrated into a revised edition of the Order and submitted to the Director of the Federal Register for approval for incorporation by reference in this section.

Place names appearing in the reporting point descriptions indicate VOR or VORTAC facilities identified by those names.
