What is the purpose of a NOTAM?

The purpose of a NOTAM (Notice to Airmen) is primarily to notify pilots of temporary flight restrictions, which may include information about changes in airspace usage, obstacles, or other conditions that could affect flight operations. This is crucial for ensuring safety in aviation, as NOTAMs provide essential information that is not widely available or may change frequently. By alerting pilots to these temporary restrictions, NOTAMs help them make informed decisions regarding their flight paths and operational procedures.

While NOTAMs can also intersect with other areas, such as notifying about specific weather-related advisories or accidents, their main function remains the communication of temporary flight restrictions. Therefore, the correct answer highlights the core role of NOTAMs in maintaining safety and efficiency in air traffic management.
