How often are NOTAMs reported?

How often are NOTAMs reported?

• A. Every 7 days
• B. Every 90 days
• C. Every 28 days
• D. Every 180 days

Answer: (C)

NOTAMs are notices about changes that could affect flight operations, and they’re issued as changes occur. In practice, the public dissemination cycle for NOTAM information is a 28-day cadence, which aligns with the periodic updating of the Aeronautical Information Publication and keeps the NOTAM system current for planning purposes. While a NOTAM can be issued at any time and remains active until canceled or until its expiry, the standard publication interval you’re expected to recall is 28 days. The other intervals don’t match how NOTAM information is typically cycled or refreshed in the system, so they don’t fit the wayNOTAM data is published and updated.
