How this entity was disambiguated
This entity first appeared as the object of triple T10363747 — 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.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Special Flight Rules Area Context triple: [SFRA, standsFor, Special Flight Rules Area]
-
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 B airspace
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.
-
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 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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Special Flight Rules Area Description of subject: Special Flight Rules Area is a designated airspace in which pilots must follow specific, often more restrictive operating procedures than those required in surrounding airspace to enhance safety and security.
