The focus on flight safety emphasizes that NOTAMs should only convey information that is pertinent to the safety of aviation operations; this is crucial for maintaining operational integrity. Furthermore, the 90-day limitation on their duration underlines the need for timely updates. Not all hazards require long-term notification, and as conditions change, it is necessary that NOTAMs are reviewed and reissued or canceled as appropriate.
