	Class G is uncontrolled airspace — airspace not designated as any other class. It typically exists from the surface up to the base of overlying Class E airspace. No ATC services are provided to any aircraft in Class G. Pilots are responsible for maintaining their own separation and must comply with VFR weather minimums, which are less stringent in Class G than in controlled airspace — particularly for low-altitude daytime flight.

	=== Class A ===		=== Class A ===

	Class A is the most restrictive class of controlled airspace. In the United States, it begins at 18,000 feet MSL and extends to FL600. '''All flights in Class A must be conducted under IFR''' — VFR flight is not permitted. An IFR flight plan must be filed and an ATC clearance received before entering. ATC provides separation to all aircraft~~. Class A is typically the domain of airline and high-performance military traffic operating in the high-altitude en route environment~~.

	=== Class B ===		=== Class B ===

	Class B airspace surrounds the busiest airports — those with the highest volume of IFR operations and passenger traffic. It typically extends from the surface up to 10,000 feet MSL and has a layered, tiered structure, sometimes described as an upside-down wedding cake. '''An ATC clearance is required for all aircraft, both IFR and VFR, to enter Class B airspace''', and ATC provides separation to all traffic within it~~. Pilots must hold at least a private pilot certificate to operate at primary Class B airports~~. Required equipment includes a two-way radio and a transponder with Mode C altitude reporting.

	=== Class C ===		=== Class C ===

	Class C airspace surrounds airports that have a control tower and radar approach control, with a significant but lower level of traffic than Class B airports~~. It typically consists of a 5 NM radius surface area and a 10 NM outer ring extending from 1,200 to 4,000 feet above airport elevation~~. Pilots must establish '''~~two-way~~ radio contact with ATC prior to entering''' Class C airspace. IFR and VFR aircraft are sequenced and separated from each other within the Class C area. A transponder with Mode C is required.		Class C airspace surrounds airports that have a control tower and radar approach control, with a significant but lower level of traffic than Class B airports.

A transponder with Mode C is required.

	=== Class D ===		=== Class D ===

	Class D airspace surrounds airports with an operational control tower but no radar approach control~~. It typically extends from the surface to 2,500 feet above airport elevation~~. Pilots must establish '''~~two-way~~ radio communications with the control tower''' before entering Class D airspace, but no ~~formal~~ clearance is required — acknowledgement of the callsign is sufficient. No separation services are provided to VFR aircraft, though controllers will issue traffic advisories. Class D becomes Class E or Class G when the tower is not in operation.

	=== Class E ===		=== Class E ===

	Class E ~~is a broad category of controlled airspace that~~ does not require communication with ATC for VFR flight. It exists in many forms: as surface areas at airports without towers, as transition areas beginning at 700 or 1,200 feet AGL around airports with instrument procedures, as the en route structure (Federal airways and RNAV routes from 1,200 feet AGL up to 18,000 feet MSL), and as airspace above 14,500 feet MSL not yet designated Class A. IFR flights in Class E receive full ATC separation services; VFR flights receive no separation but still must maintain VFR weather minimums. A transponder with Mode C is required above 10,000 feet MSL.		Class E does not require communication with ATC for VFR flight.

	Class G is uncontrolled airspace — airspace not designated as any other class. It typically exists from the surface up to the base of overlying Class E airspace ~~(usually 700 or 1,200 feet AGL, though it may extend higher in remote areas)~~. No ATC services are provided to any aircraft in Class G.

	Airspace is divided into defined categories and classes, each with its own rules governing who may fly within it, what equipment is required, what level of ATC interaction is expected, and under what conditions — VFR or IFR — flight is permitted. Understanding these classifications is fundamental to flight planning, whether in the real world or in DCS. This page covers the standard ICAO-based airspace classes used in most of the world, as well as the special use and restricted airspace designations that pilots are likely to encounter.
