ALNOTs are issued to provide information about overdue aircraft to which of the following?

ALNOTS, or Alert Notices, are crucial for coordinating the search and rescue operations for overdue aircraft. By issuing these notices to all centers and concerned facilities, it ensures a broad communication network that enhances the search efforts. This approach allows for the involvement of multiple air traffic control organizations, law enforcement, and rescue units, increasing the chances of locating the aircraft quickly.

Issuing ALNOTs to only the destination airport would limit the response capability, as they may not have the resources or reach necessary to coordinate a comprehensive search. Similarly, restricting information to neighboring facilities or just a regional center would similarly hinder the search efforts, as it wouldn’t engage the wider network of facilities that might be in a better position to assist based on their location or operational capabilities. Therefore, by alerting all centers and concerned facilities, ALNOTs maximize the response and coordination required in such critical situations.
