Upon canceling an ALNOT, what information must the originator provide?

When canceling an Alert Notification (ALNOT), it is crucial for the originator to provide the location of the aircraft if it has been found. This is because the primary purpose of an ALNOT is to inform air traffic services and other relevant parties about a potentially missing aircraft. If the aircraft has been located, providing this specific information helps ensure that all search efforts can be effectively redirected, preventing unnecessary resource expenditure and confusion. Including the aircraft's location confirms its safety and assists in the final documentation of the incident.

While other information, such as the time of cancellation or details about other aircraft in the area, may be relevant under different circumstances, providing the location of the found aircraft is the most critical piece of information needed to alleviate search and rescue operations.
