Amendment of Class D and Class E Airspace and Establishment of Class E Airspace; Clovis, NM, and Portales, NM

The FAA is proposing to amend existing Class D and Class E airspace designations at Clovis, New Mexico, and to establish new Class E airspace at both Clovis and Portales, New Mexico. These changes stem from biennial airspace reviews conducted at Cannon Air Force Base and separate reviews at Clovis Regional Airport and Portales Municipal Airport, triggered by updates to instrument flight procedures at those facilities. The proposed amendments are designed to ensure that the airspace structure accurately supports current Instrument Flight Rule (IFR) procedures and operations. This includes ensuring aircraft flying instrument approaches and departures have properly protected airspace during low-visibility or instrument meteorological conditions. Additionally, the geographic coordinates and name associated with the Cannon TACAN (Tactical Air Navigation) navigational aid will be updated to align with FAA's official aeronautical database, correcting any discrepancies that could affect navigation accuracy. This is a proposed rule at this stage, meaning the FAA is soliciting public comment before finalizing the changes. The overall impact is highly localized, affecting only the immediate airspace around two civilian airports and one military air base in eastern New Mexico.
