Future Air Navigation Systems (FANS 1/A+) provides real-time, constant position data to enhance the quality of communication between the pilot and controller, ultimately creating safer and more efficient airspace. A few benefits of FANS are as follows:

Optimized Airspace Capacity

When determining the necessary airspace separation between aircraft, errors in navigation and communication are considered. FANS equipped aircraft are enabled with CPDLC and ADS-C which dramatically increases the accuracy of navigation and communication for an aircraft, ultimately reducing separations and increasing airspace capacity.

Reduced Altitude-Loss

In an effort to avoid any collisions, aircraft must be separated by a certain altitude from any other aircraft when crossing tracks. Often times, this leads to aircraft operating below optimal altitude in order to cross a track. With increased navigational accuracy, the need for this will be greatly reduced.

Direct Routes

As a result of the FANS mandate, non-FANS aircraft are unable to transition through or fly above the North Atlantic Tracks, resulting in undesirable, inefficient routes.


Mandates

As of December 7, 2017, all aircraft flying within the North Atlantic Tracks (NAT) between FL350 and FL390 are required to be equipped with FANS 1/A+, CPDLC, ADS-C, VHF datalink or SATCOM systems. On January 31, 2020, the flight requirement expanded to FL290 and above, ultimately reserving the best, most efficient airspace for FANS equipped aircraft only.

Timeline for North Atlantic Track System FANS 1/A+ Mandates

Currently, there are no FANS 1/A+ mandates for the United States or European domestic airspace.
