Which facility should not be notified when experiencing air safety issues?

The choice to notify the airport manager's office regarding air safety issues is critical, as they are responsible for the overall operations and safety at the airport. This facility can coordinate with other relevant entities to address any immediate safety concerns and manage the situation effectively.

Notifying the ARTCC (Air Route Traffic Control Center) is equally important because they oversee air traffic in controlled airspace and can implement appropriate measures to ensure safety during the incident, including rerouting aircraft as necessary.

The military office may also need to be informed in certain situations, especially if military operations or airspace are involved, or if military aircraft might be affected.

The NAVAID (Navigational Aid) maintenance crew, however, should not be notified of air safety issues unless the issue specifically relates to the functioning of navigation aids they manage. In general, they are focused on the maintenance and integrity of navigational equipment rather than directly managing air safety concerns. Thus, they typically wouldn’t need to be alerted unless the incident had a direct connection to the navigational aids they maintain.
