What the agency says
This action proposes to amend Class D and Class E airspace over Tri-Cities, TN. This action would modify the dimensions of the Tri-Cities, TN Class D and Class E2 airspace to appropriately contain Instrument Flight Rules (IFR) operations at the Tri-Cities Airport. This action would also remove the Tri-Cities, TN Class E4 airspace, as it is no longer necessary. This action would also modify the Tri- Cities, TN Class E5 airspace to appropriately contain IFR operations at the airport. This action would also update verbiage in the Class D and Class E2 airspace legal descriptions to comply with current FAA guidance. This action would also update the airport name for Tri-Cities Airport in the Class D, Class E2, and Class E5 airspace legal descriptions.
