What is the difference between fans and ATN?

What is the difference between fans and ATN?

ADS for FANS is known as ADS-C (ADS Contract) and allows an automatic handshake by contract between the aircraft and enroute ATC for DataLink. ATN-B2 includes advanced services such as 4D Trajectories, Dynamic RNP and Advanced Flight Interval Management with ATC winds.

What is ATN B1?

Telecommunication Network (CPDLC-ATN B1) This 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.

What is CPDLC ATN?

Protected Mode (PM-CPDLC), used by Link 2000+, allows the flight crew to select from a menu of standard ATC communications to send and receive messages via text.

What is the difference between fans and CPDLC?

FANS 1/A consists of CPDLC and ADS-C. CPDLC allows communications between the pilot and ATC and ADS-C is an electronic contract, valid through the duration of time the aircraft is in FANS 1/A airspace, offered by ATC and accepted by the flight crew. FANS-1 is Boeing’s solution and FANS-A is the Airbus solution.

Does CPDLC use HF?

CPDLC is a method by which ATC can communicate with pilots over a data link system, increasing the effective capacity and improving the availability of the communications channel. It is intended to supplement traditional voice over VHF and HF radio frequencies, and free up voice radio channels.

Is Cpdlc mandatory?

Controller Pilot Data Link Communications (CPDLC) are currently required in Datalink Mandated (DLM) airspace within the North Atlantic Tracks (NATs). As of Dec 7, 2017, airspace impacted by CPDLC requirements will expand and this will affect general aviation (GA) transatlantic operations.

Are there fans on airplanes?

Both the new Airbus A380 and Boeing 787 have FANS-1/A capability. ATC services are now provided to FANS 1/A equipped aircraft in other oceanic airspaces, such as the North Atlantic. The Airbus ICAO compliant product for the A320 family is known as FANS-B.

What do you need to know about fans and ATN?

Domestically, rather than adopt an ATN-only based solution, the FAA has opted for a longer-term solution combining FANS with ATN (as CPDLC). This dual stack aircraft structure has both FANS 1/A and ATN-B1 Data Comm systems installed with the goal of seamless operations (FANS 1/A+).

What does Data Comm fans 1 / a + mean?

“FANS 1/A.” With the addition of minor enhancements it has now become known as FANS 1/A+. Data Comm FANS today uses automatic position reporting and CPDLC to directly communicate to ATC over VHF using VDL Mode 2 or SATCOM (Inmarsat or Iridium) in lieu of ACARS, to enable more efficient communications between the aircraft and ATC.

When did the Nat start requiring fans 1 / a +?

aircraft operating in that airspace. Mandates for FANS 1/A+ began in 2013 for the most efficient tracks in the North Atlantic. In 2015, this was expanded and all of. the NAT required FANS 1/A+ technology at optimum altitudes, which increased to most of the North Atlantic airspace between. FL350 and FL390 in March 2018.

What does fans 1 / a + do for aircraft?

used to enable digital transmission of short, relatively simple messages between the aircraft and ATC. FANS 1/A+ is a requirement in the North Atlantic in the core tracks and is expanding to additional tracks and airspaces. The ADS-C capability is largely a transparent capability.
