True or False: The NOTAM system is used for permanent changes in the National Airspace System.

The NOTAM (Notice to Airmen) system is designed to provide timely information about temporary changes that may affect flight operations within the National Airspace System. It is not intended for permanent changes; instead, it addresses short-term or urgent updates regarding aeronautical facilities, services, or procedures. This system plays a critical role in ensuring that pilots are informed about conditions that could impact their flights, such as runway closures, unserviceable navigational aids, or temporary airspace restrictions.

Permanent changes to airspace or related procedures are typically documented through official published documents and updates to regulatory guidance, rather than through the NOTAM system. Therefore, the assertion that the NOTAM system is used for permanent changes is incorrect. This distinction is fundamental to understanding the operational environment in which pilots and air traffic controllers operate.
