Whether flying a commercial airliner across the continent or a small private plane on a local journey, every flight must comply with the FAA’s regulations, making this agency the ultimate authority in managing the nation’s skies.

Controlled, Uncontrolled, and Special Use

The airspace is broadly categorized into three main types: controlled, uncontrolled, and special use. Each type serves a specific purpose and is subject to distinct regulations to ensure the safe and efficient movement of aircraft.

The Controlled Type

Controlled Type is a designated area where air traffic control (ATC) services are provided to regulate the flow of aircraft. Within this controlled type, pilots must maintain two-way radio communication with air traffic controllers and follow their instructions for maintaining separation, obtaining clearances, and adhering to other safety protocols. Controlled sky is further divided into various classes (Class A, B, C, D, and E), each with its own set of rules and requirements regarding communication, equipment, and pilot qualifications.

Class A airspace covers the highest altitudes, typically above 18,000 feet, and is exclusively for instrument flight rules (IFR) operations. Class B surrounds the busiest airports, while Class C encompasses smaller airports with moderate traffic. Class D is found around towered airports, and Class E covers the remaining controlled airspace not designated as A, B, C, or D.

The Uncontrolled Type

In uncontrolled skies, air traffic control services are not provided, and pilots are responsible for maintaining situational awareness and separating themselves from other aircraft. Communication with ATC is not required, but pilots must still follow specific regulations, such as operating under visual flight rules (VFR) and adhering to right-of-way rules. Uncontrolled type is typically found in less congested areas and is often used by smaller aircraft and general aviation pilots for activities like sightseeing, aerial photography, or recreational flying.

Special Use Type

Special use airspace is a designated area where specific activities, such as military operations, aerial gunnery, or other hazardous activities, take place. This type may be temporary or permanent and can have restrictions or limitations on civilian aircraft operations. Examples of special use airspace include restricted areas, prohibited areas, warning areas, military operations areas (MOAs), and alert areas. Pilots must be aware of the rules and limitations associated with each type and obtain proper clearances or avoid these areas as required.

By understanding and adhering to the regulations governing these three main types, pilots, air traffic controllers, and other aviation professionals can ensure the safe and efficient operation of aircraft in the national airspace system.

Categories and Classification from A to G

The Federal Aviation Administration (FAA) has classified airspace into seven distinct categories, each with its own set of rules, requirements, and restrictions for aircraft operations. This classification system, ranging from Class A to Class G, helps ensure the safe and efficient management of air traffic within the National Airspace System (NAS).

Class A

Class A is the most restrictive category, encompassing the airspace from 18,000 feet mean sea level (MSL) up to and including flight level (FL) 600 (approximately 60,000 feet). All aircraft operating in Class A must be equipped with a mode C or mode S transponder and must operate under instrument flight rules (IFR). Additionally, pilots must receive an air traffic control (ATC) clearance and maintain two-way radio communication with ATC facilities.

Class B

Class B surrounds the busiest airports in the United States, serving as a protective layer for high-density air traffic operations. Class B typically extends from the surface up to 10,000 feet MSL. Aircraft operating within Class B must be equipped with a mode C or mode S transponder, maintain two-way radio communication with ATC, and follow specific procedures for entering and exiting the airspace.

Class C

Class C is established around airports with moderate to high levels of air traffic, typically those with operational control towers and radar approach control services. Class C extends from the surface up to 4,000 feet above the airport elevation. Aircraft operating within Class C must establish two-way radio communication with ATC, maintain appropriate transponder codes, and follow specific procedures for entering and exiting the airspace.

Class D

Class D is designated around smaller airports with an operational control tower. Class D extends from the surface up to 2,500 feet above the airport elevation. Aircraft operating within Class D must establish two-way radio communication with the control tower and receive clearance before entering or exiting the airspace.

Class E

Class E is a catch-all category that includes controlled airspace not designated as Class A, B, C, or D. It extends from the surface or a designated altitude up to 18,000 feet MSL, or the lower limit of overlying Class A airspace. Class E may require pilots to operate under IFR or visual flight rules (VFR), depending on the specific area and altitude.

Class F

Class F is designated for use by the military and other government agencies for specific activities, such as air combat training or aerial gunnery exercises. Civilian aircraft may be restricted or prohibited from entering this airspace during certain operations or time periods.

Class G

Class G is considered uncontrolled airspace and includes the remaining airspace not designated as any other class. It typically extends from the surface up to 14,500 feet MSL or the base of overlying controlled airspace. Aircraft operating within Class G must follow VFR and are responsible for maintaining situational awareness and separating themselves from other aircraft.
