How do ATC controllers use NOTAMs?

ATC controllers utilize NOTAMs (Notices to Airmen) primarily to stay informed of operational changes or potential hazards that could affect the safety and efficiency of flight operations. NOTAMs provide critical information about closed runways, navigational aid outages, airspace restrictions, and other factors that could impact a flight's route or landing. By being aware of these updates, controllers can make informed decisions about managing air traffic, directing aircraft effectively, and ensuring the overall safety of aviation operations. This function is essential as it allows ATC to communicate current conditions to pilots and facilitate safe navigation in the airspace.

In contrast, while navigational training and pilot feedback are important aspects of aviation, they are not the primary purpose of NOTAMs. Similarly, NOTAMs are not used to create flight plans; that is typically done by pilots based on aeronautical charts and other resources. The role of NOTAMs is centered around the dissemination of time-sensitive operational information indispensable for maintaining safety in aviation.
