ICAO AIRSPACE CLASSIFICATIONS

Airspace classification is designated by the letters (A) thru (G). Classification (A) represents the highest level of control and (G) represents uncontrolled airspace. The definition of each classification is found in the Glossary portion of this section and the Enroute and Air Traffic Control section of this manual. The airspace classification letter is displayed in association with the airspace type and vertical limits.
