What is FANS/CPDLC?
Future Air Navigation System (FANS) technology is a form of Controller to Pilot Data Link Communications (CPDLC) that uses the Aircraft Communications Addressing and Reporting System (ACARS) network for air traffic controller to pilot text messaging. Primarily, it has been designated for use over the North Atlantic Tracks (NAT) oceanic airspace. However, some of the functionality is currently being pushed into the domestic United States as part of the Data Comm initiative for the FAA’s NextGen program. Europe is using Protected Mode CPDLC (PM CPDLC) or Link 2000+, which is similar to FANS. Link 2000+ is a form of pilot to controller data link communications that uses the Aeronautical Telecommunication Network (ATN)
Since the final phase of the North Atlantic Datalink Mandate (NAT DLM) came into effect on 30 Jan 2020, CPDLC is now required between FL290-FL410 throughout the entire NAT region. Simply put, you must be equipped with CPDLC and ADS-C if you want to fly between these flight levels.
How does it work?
The Future Air Navigation System (FANS) provides direct datalink communication between the pilot and air traffic control (ATC). Radio or satellite technology (SatCom) is used to enable digital transmission of short, relatively simple messages between the aircraft and ground stations. The CPDLC application allows the crew to communicate with Air Traffic Control centers through formatted data link messages, as a complement (and future substitute) to standard VHF voice communications.

Benefits
The goal is to automate routine tasks that currently require multiple voice/radio exchanges. Pilots and ATC will be able to exchange reports, instructions, and flight requests in a digital, text-based format instead of relying on voice communications. Voice communications can pose significant problems in flight, with language and accent issues the communication can produce safety and delays during the flight. Text-based messages are clear and concise and provide a benefit to the crew.
Efficiency
Increased fuel and time efficiency by improving air traffic routing.
Safety
Safer airspace by improving visibility and situational awareness..
Details
As of February 2020, FANS/CPDLC is now required to fly at altitudes in all airspace above FL290. Future mandates will be on the horizon so ensure you have the proper equipment installed that is upgrade-able for the future!
