## Abstract

This action amends Class D and Class E airspace at Baltimore, MD, as the Martin Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures have been developed at Martin State Airport. This action also updates the geographic coordinates of the Baltimore VORTAC and makes a minor adjustment to the geographic coordinates of the airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
