• B. NOTAM D is limited to the airfield; NOTAM L covers international airspace.
• C. NOTAM D is a weather advisory; NOTAM L is a security advisory.
• D. NOTAM D and NOTAM L are the same thing; no difference.

Answer: (A)

NOTAM scope determines who needs to act on the information. Distant NOTAMs are advertised broadly through the national NOTAM system to pilots and operators who fly across multiple airports or regions. They cover items that aren’t limited to a single field, such as outages of navigation aids or airspace changes that could affect more than one airport. Local NOTAMs stay at the field level, concerns a single airport and its immediate vicinity, and address conditions like a runway closure or construction at that specific field. Because of this difference in reach and audience, Distant NOTAMs are nationwide/global in dissemination, while Local NOTAMs are confined to a particular airfield.
