Target entity: Class B airspace Context triple: [Potomac TRACON, controlsAirspaceType, Class B airspace]
-
A.
Class B airspace
chosen
Class B airspace is a highly controlled airspace surrounding the nation’s busiest airports, designed to manage dense traffic with strict entry and communication requirements for pilots.
-
B.
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.
-
C.
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.
-
D.
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.
-
E.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
