What is the purpose of NOTAMs in tower operations?

• A. NOTAMs provide weather forecasts and runway conditions
• B. NOTAMs provide routine gate assignments for arrivals
• C. NOTAMs provide notices of maintenance tasks for the day
• D. NOTAMs provide timely information about airport or airspace changes and hazards that may affect operations

Answer: (D)

NOTAMs convey timely information about changes to airport or airspace and any hazards that could affect operations. They are not weather forecasts, gate assignments, or routine maintenance notes. In tower operations, NOTAMs alert you to temporary runway or taxiway closures, outages of navigation or approach aids, lighting or beacon outages, and any temporary airspace restrictions or construction that could alter standard procedures. This information lets you adjust flight sequencing, routing, and ground movements to maintain safety and efficiency despite the temporary changes.
