When shall using agencies submit NOTAM requests for activities within non-DOD controlled international airspace?

• A. At least 2 weeks prior
• B. No earlier than 3 days prior
• C. Immediately
• D. At least 1 month prior

Answer: (A)

The main idea here is giving airspace users enough advance notice to plan and adjust for planned activities in international airspace not under DoD control. The recommended lead time is at least two weeks. This window allows proper coordination with foreign civil aviation authorities, preparation and validation of the NOTAM data, and dissemination through international NOTAM channels so pilots have reliable information well in advance. Submitting immediately or within a few days wouldn’t provide sufficient lead time for international coordination and widespread notice, while requesting a month or more ahead is often more than what’s needed for typical activities.
