Class D is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) air space designation. Class D airspace areas are designed to improve aviation safety by reducing the risk of mid-air collisions with a control tower. [ 1 ]
Class D airspace is generally cylindrical in form and normally extends from the surface to 2,500 feet (760 m) above the ground. Airspace within the given radius, but in surrounding class C or class B airspace, is excluded. Class D airspace reverts to class E or G during hours when the tower is closed, or under other special conditions. [9]
Class D airspace exists from the surface to 2,500 ft. AGL above an airport. Class D airspace only surrounds airports with an operational control tower. Class D airspace is also tailored to meet the needs of the airport. Pilots are required to establish and maintain two-way radio communications with the ATC facility providing air traffic control ...
It also overlays Class D airspace at smaller airports. Class D is used for the Terminal Control Zones of medium-sized airports, extending from the surface up to 2,500 feet (760 m) AGL (depicted in MSL on a chart). Above this, Class C airspace is used, although generally only in a sector, and not 360° around the airport.
In United States aviation, a terminal radar service area (TRSA) is a delimited airspace where radar and air traffic control services are made available to pilots flying under instrument flight rules or (optionally) visual flight rules, to maintain aircraft separation. TRSAs most often surround busy U.S. airports.
It is the opposite of controlled airspace. It is that portion of the airspace that has not been designated as Control Area, Control Zone, Terminal Control Area or Transition Area. [1] According to the airspace classes set by the International Civil Aviation Organization (ICAO), the uncontrolled classes of airspace are class F and G. [2]
