NOTAM Ds are NOTAMs that require local and distant dissemination.

• A. True
• B. False
• C. Not specified
• D. Not applicable

Answer: (A)

NOTAM D is designed for wide dissemination to the flight community, reaching both local users at a field and pilots and operators that are farther away. This broad distribution ensures anyone planning or flying through the area is aware of changes that could affect safety, such as runway closures, lighting outages, or NAV aid issues. Other NOTAM types are more restricted in scope—local NOTAMs cover only a single aerodrome area, and NOTAMs not disseminated to the flight community are limited to non-operational audiences—so they do not meet the requirement of local and distant dissemination.
