Name	Data Type	Definition
type	CodeAirspaceType	An indicator of the general structure or characteristics of a particular airspace. Where airspace is a defined three dimensional region of space relevant to air traffic.
designator	CodeAirspaceDesignatorType	A published sequence of characters allowing the identification of the airspace. Where airspace is a defined three dimensional region of space relevant to air traffic.
localType	TextNameType	A type designator used locally (inside a State or a Region) for a particular airspace sub-category. Where airspace is a defined three dimensional region of space relevant to air traffic.
name	TextNameType	The name given to an airspace by a responsible authority. It should be written as published, with no significance to upper or lower case letters. Where airspace is a defined three dimensional region of space relevant to air traffic.
designatorICAO	CodeYesNoType	An indicator of whether an Airspace Designator is recorded in ICAO Doc. 7910, 'Location Indicators'. Where airspace is a defined three dimensional region of space relevant to air traffic.
controlType	CodeMilitaryOperationsType	The primary organization type in terms of civil or military, providing air traffic services within a designated airspace. Where airspace is a defined three dimensional region of space relevant to air traffic.
upperLowerSeparation	ValFLType	A flight level (e.g., 18000 feet MSL) that indicates the division of airspace between lower and upper airspace.
