Proposed Amendment of Class D and Class E Airspace; Atwater, CA

This action proposes to amend Class D airspace, and Class E airspace extending upward from 700 feet above the surface at Castle Airport, Atwater, CA, to accommodate airspace redesign due to the decommissioning of the El Nido VHF Omnidirectional Range/Distance Measuring Equipment (VOR/DME) as the FAA transitions from ground-based to satellite-based navigation. Also, this action would update the airport's geographic coordinates to match the FAA's aeronautical database. This action also would make an editorial change to the Class D airspace legal description replacing ``Airport/Facility Directory'' with the term ``Chart Supplement''. These actions are necessary for the safety and management of instrument flight rules (IFR) operations at the airport.
