This action proposes to establish Class C airspace and remove Class D airspace at Wilmington International Airport (ILM), NC. Operating requirements within Class C airspace keep ATC informed of all aircraft operating within the Class C airspace. Class C airspace enhances safety by the requirement that two‐way radio communication must be established with ATC prior to a pilot entering Class C airspace and maintained for the duration of flight in Class C airspace. Class C airspace is designed to keep ATC informed of all aircraft operating within the Class C airspace. Pilots are required to establish two-way radio communications with ATC prior to entering Class C airspace, and they must maintain communications while operating in Class C airspace.
