Class A Airports The airspace around some of the worlds busiest airports is classified as ICAO Class A. This protects the approach and departure paths not only from aircraft not under Air traffic control but keeps out all traffic not on active instrument flight plans. All aircraft inside Class A airspace are subject to Air traffic control. Traffic must be operating under IFR. An airport may be in Class A airspace if it is slot-controlled to prevent congestion. Some may be Class A in the interests of national security such as Tel Aviv Ben Gurion. In other cases such as London Heathrow it is simply a legacy from the days prior to the ICAO standard airspace classes.

No airports in the United States are Class A although Reagan National near Washington DC has had "temporary" restrictions on incoming traffic that are similar since 9/11.

In some cases, traffic operating under a Special Visual Flight Rules clearance may be allowed to operate in the Class A airspace, if the aircraft is not equipped or the pilot not qualified to fly under IFR.
