Federal Aviation Administration November 13, 2015 – Federal Register Recent Federal Regulation Documents

This action proposes to modify Class D airspace, Class E airspace extending upward from 700 feet above the surface, and remove Class E surface area airspace designated as an extension at Chico Municipal Airport, Chico, CA. After reviewing the airspace, the FAA found it necessary to amend the airspace area by increasing the Class E airspace extending upward from 700 feet above the surface for the safety and management of Instrument Flight Rules (IFR) operations for arriving and departing aircraft at the airport. The FAA found no standard instrument approach procedures requiring Class E surface area airspace designated as an extension to Class D airspace. This action would also change from navigation aid to geographic coordinate references in the legal description, in anticipation of the FAA's future navigation aid discontinuance plan. The geographic coordinates of Chico Municipal and Ranchaero Airports also would be updated for the Class D and E airspace areas noted above.

This action proposes to modify Class E surface area airspace designated as an extension to Class C airspace, and Class E airspace extending upward from 700 feet above the surface at Boise Air Terminal/ Gowen Field Airport, formerly Boise Air Terminal (Gowen Field), Boise, ID. After reviewing the airspace, the FAA found standard instrument approach procedures are not fully contained in controlled airspace, thereby necessitating airspace redesign for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This proposal also would update the name of the airport to match the FAAs aeronautical database.
