ADIZ

Air Defence Identification Zone. Special designated airspace of defined dimensions within which aircraft are required to comply with special identification and/or reporting procedures additional to those related to the provision of air traffic services (ATS). Description: ICAO Recognized.

Semantic Correspondence

ADV

Advisory Area. An area of defined dimensions within which air traffic advisory service is available. Description: ICAO Recognized. Air traffic control service provides a much more complete service than air traffic advisory service advisory areas and routes are therefore not established within controlled airspace, but air traffic advisory service may be provided below and above.

AMA

Minimum altitude area. The lowest altitude to be used under instrument meteorological conditions (IMC) which will provide a minimum vertical clearance of 300 m (1 000 ft) or in designated mountainous terrain 600 m (2 000 ft) above all obstacles located in the area specified. Description: ICAO Recognized. Published by many States as rectangles of 1 x 1 degree on the ENR 6 charts. Note - In the exact calculation 984 feet can be used as an equivalent to 300 metres.

Semantic Correspondence

MTR

Military Training Route buffer. A control area or portion thereof, established in the form of a corridor around a military training route in order to protect it from other traffic.

Semantic Correspondence

NAS

National Airspace System. [note: The airspace within which a State provides Air Traffic Services is usually composed of:1) the territories over which the State has jurisdiction 2) those portions of the airspace over the high seas or in airspace of undetermined sovereignty where the provision of ATS are provided as determined by regional agreements. It can usually be determined by the UNION of FIRs (including, where appropriate, NO-FIRs) of the UNION of NAS-P. .]
