The world's navigable airspace is divided into three-dimensional segments, each of which is assigned to a specific class. Most nations adhere to the classification specified by the International Civil Aviation Organization (ICAO) and described below, though they might use only some of the classes defined below, and significantly alter the exact rules and requirements.
The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations.
Class B is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) airspace designation. Class B airspace areas are designed to improve aviation safety by reducing the risk of midair collisions in the airspace surrounding airports with high-density air traffic operations. [1]
Class A airspace is generally the airspace from 18,000 feet (~3.4 miles, 5.5 km) mean sea level (MSL) up to and including flight level (FL) 600 (~11.4 miles, 18.3 km), including the airspace overlying the waters within 12 nautical miles (NM) (~13.8 miles, 22.2 km) of the coast of the 48 contiguous states and Alaska. Unless otherwise authorized ...
The ICAO airport code or location indicator is a four-letter code designating aerodromes around the world. These codes, as defined by the International Civil Aviation Organization and published quarterly in ICAO Document 7910: Location Indicators, are used by air traffic control and airline operations such as flight planning.
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 C is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) air space designation. Class C airspace areas are designed to improve aviation safety by reducing the risk of mid-air collisions in the terminal area and enhance the management of air traffic operations therein. [1]
Pilots must also receive clearance to enter the Class B airspace but Visual Flight Rules may be used, unlike in Class A airspace. Class B airspace corresponds to the area formerly known as a Terminal Control Area or TCA. [6] Class C airspace reaches from the surface to 4,000 ft. AGL above the airport which it surrounds.
