What is the purpose of a Notice to Airmen (NOTAM)?

The purpose of a Notice to Airmen (NOTAM) is to inform pilots about any hazards, changes, or essential information regarding airspace. NOTAMs are critical tools in aviation safety as they convey timely updates about conditions that could affect flight operations, such as construction on runways, changes in airspace usage, or changes in navigational aids. By keeping pilots informed about these key aspects, NOTAMs help ensure safe and efficient flight planning and operations.
