FAA tweaks Denver airspace
The FAA published a modification to Class E airspace at Denver International Airport, a regulatory change that can affect flight‑test corridors and access for high‑speed demos. Changes like this alter where and how companies can schedule UAV, hypersonic experiment corridors or supersonic demonstrations (federalregister.gov).
Effective date set for 0901 UTC on July 9, 2026, filed as a final rule under Docket No. FAA‑2025‑5384, Airspace Docket 25‑ANM‑144, RIN 2120‑AA66. (govinfo.gov) The rule revises the transitional Class E description by extending the portion that begins at 700 feet above the surface and removing the portion that begins at 1,200 feet above the surface at Denver International Airport. (federalregister.gov) The FAA issued the NPRM on December 30, 2025 (90 FR 61105) and opened a public comment period on the proposal. (govinfo.gov) The agency’s final rule text notes that interested parties were invited to comment and that no comments were received on the proposal. (dateas.com) An administrative amendment to the airport’s Class E legal description is included, and the change will be incorporated by reference into FAA Order JO 7400.11K (Airspace Designations and Reporting Points) pending that order’s annual revision. (govinfo.gov) The FAA described the amendment as supporting the safety and management of IFR operations, with the transitional Class E serving to contain IFR traffic operating to and from Denver and surrounding airports. (govinfo.gov) All rulemaking documents, including the NPRM, background material, and the docket, are posted on Regulations.gov under FAA‑2025‑5384, and the FAA lists Nathan A. Chaffman at the Western Service Center (phone (206) 231‑3460) as the contact for further information. (govinfo.gov)
