Which NOTAM type is missing from the list of Aerodrome, CZNB, National, and Local NOTAMs?

• A. Special Use Airspace NOTAM
• B. Flight information region NOTAM
• C. Provincial NOTAM
• D. Emergency NOTAM

Answer: (B)

Notams are categorized by how broadly they apply. Aerodrome NOTAMs concern a single airport, Local NOTAMs cover a nearby area around that airport or region, and National NOTAMs span a country. A Flight Information Region NOTAM, on the other hand, applies to the entire FIR, which is a much larger geographic area that can cross national borders. Because the list already includes an aerodrome, a specific FIR (CZNB), and local and national scopes, the missing type that completes the common scope levels is the FIR-wide NOTAM. The other options describe specialized or situational categories (special use airspace, provincial, emergency) and are not the broad scope category that defines FIR-wide dissemination.
