ICAO airspace classes
E1175426
UNEXPLORED
ICAO airspace classes are a standardized global system that categorizes airspace into lettered classes (A through G) to define rules, separation requirements, and services for different types of air traffic.

How this entity was disambiguated
This entity first appeared as the object of triple T15755485 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: ICAO airspace classes Context triple: [Norwegian airspace, classifiedAccordingTo, ICAO airspace classes]
-
A.
Class A airspace
Class A airspace is the highest controlled airspace layer in the United States, typically used for high-altitude en route flight under instrument flight rules (IFR) by commercial and other high-performance aircraft.
-
B.
Class D airspace
Class D airspace is a category of controlled airspace surrounding smaller airports with an operational control tower, where pilots must establish two-way radio communication with air traffic control before entering.
-
C.
Class E airspace
Class E airspace is a category of controlled airspace that typically begins at various altitudes above the surface and extends up to but not including Class A airspace, where IFR and many VFR operations are managed under air traffic control.
-
D.
Class C airspace
Class C airspace is a category of controlled airspace around busy airports that requires two-way radio communication and air traffic control clearance for participating aircraft.
-
E.
Class G airspace
Class G airspace is uncontrolled airspace where air traffic control does not provide separation services, and pilots operate primarily under visual flight rules with minimal regulatory requirements.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
