The Desired End-State The North Atlantic System Planning Groups (NAT SPGs) policy maintains that Standards and Recommended Practices (SARPs) compliant Aeronautical Telecommunication Network (ATN) data link technologies remain the desired end-state but greater flexbility has been agreed to for the use of other non-SARPs compliant technologies, in particular FANS-1/A.

Automatic Dependent Surveillance (ADS) Prior to the implementation of ADS – all flights, FANS equipped or not, had to make position reports at approximately every 10 degrees This took up a great deal of frequency time

CPDLC Phase 1, 2 & 3 Phase 1 –Flight crews use data link to request speed and level changes and receive a response via voice Phase 2 –Flights receive VHF domestic frequency assignments via CPDLC Phase 3 –Flights receive clearances and response to clearance requests via CPDLC

HFDL (HF Data Link) The HFDL issue is becoming more prominent as airlines are showing more and more interest in Polar flights and HFDL is the sole data link media that can provide continuous coverage over the Arctic region, therefore FANS operations there will have to rely on this media.
FMC WPR FMC Waypoint Position Reports (WPRs) are currently being looked at in the North Atlantic. Alternative for non-FANS equipped aircraft.
Human Factors & Transition Issues Transition to data link is not initially a time-saver Once pilots and operators get used to the system and procedures it does become a time-saver
Oceanic Clearances and Data Link Canada and The United Kingdom have indicated that they plan to implement voiceless Oceanic Clearance Deliveries by the end of 2004
ATN in the North Atlantic Consideration of using ATN equipped B aircraft in CPDLC trials
