How should NOTAMs that affect both civil and military users be issued?

• A. As military NOTAMs
• B. As international NOTAMs
• C. As civil NOTAMs
• D. As combined civil/military NOTAMs

Answer: (C)

When information affects both civil and military users, it should be issued through the civil NOTAM system. Civil NOTAMs are the standard channel for publishing notices that impact civil aviation, and they are distributed through the international civil-notice network. Military operators typically access these civil NOTAMs via liaison channels and coordination with civil authorities, so issuing the notice as a civil NOTAM ensures timely, consistent dissemination to all users without creating separate, potentially conflicting messages. While some systems may support a combined civil/military NOTAM category, the common practice for cross‑audience information is to publish it as a civil NOTAM to guarantee broad, uniform visibility.
