Amendment of Class D Airspace and Class E Airspace Over Groton, CT

What it does

This action proposes to amend Class D and Class E airspace over Groton, CT. This action would reduce the radius of the Groton, CT, Class D airspace to a 4.2-mile radius of the airport, excluding that airspace within a 1-mile radius of the Elizabeth Field Airport, Fishers Island, NY. This action would update the geographic coordinates for the Groton-New London Airport, Groton, CT, and the Elizabeth Field Airport, Fishers Island, NY, in the associated airspace legal descriptions. This action would also update the airport name for Elizabeth Field Airport in the Groton, CT, Class D airspace legal description. This action would also replace "Airport/Facility Directory" in the Groton, CT, Class D airspace legal description with "Chart Supplement" to comply with current FAA guidance. This action would also remove the exclusions of adjacent Class E airspace areas from the Groton, CT, and Fishers Island, NY, Class E airspace legal descriptions to comply with current FAA guidance.
