• A. National Operational and Traffic Assessment Network
• B. Notation of Airborne Timings and Mechanisms
• C. Networked Observations for Aircraft and Traffic
• D. Notice to Airmen, a notice disseminating timely information affecting flight operations and safety.

Answer: (D)

NOTAMs are notices sent to aircrews to relay timely information that could affect flight operations and safety. The acronym expands to “Notice to Airmen.” Historically, these notices were issued to airmen, and today they warn about conditions like runway closures, navigation aid outages, airspace restrictions, or changes to instrument approaches. They’re distributed quickly to pilots, dispatchers, and operations centers so flights can be planned and carried out safely. Other phrasings don’t match the official expansion of the acronym or the purpose of these notices, which is to alert crews to information that could impact safety and operations.
