Air Traffic Services Inter-facility Data Communication
Introduction:

The AIDC application supports information exchanges between ATC application processes within automated ATS systems located at different ATSUs. This application supports the Notification, Coordination, and the Transfer of Communications and Control functions between these ATSUs.

Flight States
• Pre-Notifying: Flight plan information may have been received. Any previously received notification and coordination information for the given flight cancelled by a MAC is no longer relevant.
• Notifying: The aircraft's progress is being monitored by one or more non- controlling ATSUs, in addition to the controlling ATSU.
• Negotiating: Coordination data is being exchange between the controlling ATSU and the receiving ATSU as part of the initial coordination dialogue.
• Coordinating: Abbreviated coordination data has been sent to the receiving ATSU.
• Coordinated: Coordination of the boundary crossing conditions is completed.
• Re-Negotiating: Coordination data is being exchange between the controlling ATSU and the receiving ATSU as part of a later coordination dialogue.
• Transferring: Air traffic control responsibility for the aircraft is in the process of being transferred to the receiving ATSU.
• Transferred: Air traffic control responsibility for the aircraft has been transferred to the receiving ATSU.
