TRANSCRIPT
Technical White Paper – CPDLC Data Link
With global air traffic expected to double in the next 20 years to over 1 billion flights, upgrades to Air Traffic Control systems will become necessary in order to prevent reductions in airspace efficiencies whilst maintaining acceptable levels of safety. Additional requirements for data link on aircraft are anticipated over the next 5-10 years to meet this need for new traffic management systems.
Data link solutions provide airline operators with significant benefits at reduced cost, including enhanced flight operations efficiency and lower airline maintenance, administration and air traffic control costs.
With new statistics and headlines relating to increased air traffic and the environmental damage this causes being published on an almost daily basis, it is evident that air traffic management systems in Europe and the United States need to be modernised. The response of the US and the European Union to this situation is equally well documented, with both EUROCONTROL and the FAA taking the lead in the modernisation of the ATM EcoSystem. The Single European Sky ATM Research (SESAR) is currently in its development phase (2009-2016) with initial deployment in some technology areas already progressing. Once complete, this should facilitate a threefold increase in capacity and a 50% reduction in air navigation costs, as well as a reduction in an aircraft’s environmental impact by up to 10% per flight.
The Federal Aviation Administration’s (FAA) Next Generation Air Transportation System (NextGen) is the US equivalent to SESAR. This system will be implemented in stages between 2012 and 2025, and will save 1.4 billion gallons of fuel and 14 million tonnes of CO2 by 2018. The system is anticipated to reduce delays by 35%, adding up to $23 billion in benefits by 2018 compared with 2010, according to the FAA. Data link solutions represent the key to future global Air Traffic Management (ATM) systems, and both SESAR and NextGen are defining the standards and validating the systems of tomorrow, today. The Single European Sky - Data Link Services (Link 2000 / SES-DLS) is being deployed now. The aircraft improvements defined and validated during the development phase of SESAR will start to be deployed in the 2016-2018 timeframe.

Data Communications
1
Although complex in name, PM-CPDLC is straightforward in practice: similar to text messaging on cell phones, this system allows pilots and Air Traffic Control to send canned data messages between the ground and the aircraft. CPDLC messages enable routine tasks that can take up to 50% of a controller’s time to be automated. Messages include standard ATC clearances “ACL” (e.g. “Climb to level 350”) or “AMC” (e.g. microphone check) and are intended to augment ATC voice communications and provide additional air traffic control capacity in high density ATC environments.
CPDLC is not a new technology, and air traffic controllers and pilots have been using these “text” messages for many years in the existing Future Air Navigation System 1/A (FANS1/A), used in trans-oceanic flights.
There are various forms of data link in operation today, including AOC, ATC, ADS as part of ATS, FIS (D-ATIS) and A623 applications that include D-ATIS. In addition, clearances such as Pre-Departure Clearances are supported via A623 messages. The European Commission mandated the installation of Protected Mode Controller Pilot Data Communication (PM-CPDLC) for forward fit aircraft starting from January 1, 2011.
This mandate is the first of a number of expected compulsory upgrades to the data link systems on aircraft. The SES-DLS mandate is expected to be followed by additional data link requirements.
— FAA’s NextGen Air Traffic Management System requirements
are expected in 2014. Initial deployment is expected to be centered on FANS 1/A+ with VDL Mode 2, followed by harmonisation with Europe by 2025 as reflected in NextGen Advisory Committee (NAC), dated 02/2012.
— SESAR requirements in work (SC-214), project operational usage starting in the 2016-2018 time frame. The Airbus plan is to have an ATSU capable of SC214 in 2016.
— North Atlantic Tracks will have preferred routings for FANS1/A equipped aircraft from 2013 on limited tracks, and from Feb.2015 on two core NAT tracks above FL340

Note : N/A = Not Applicable or Not Available (the OEM did NOT provide such a function for the aircraft). Standard means the a/c as delivered from the OEM would have that capability, OPTION is that function is a current (or soon to be available OPTION), and Future Option means exactly that (a PLANNED future option from the OEM, but not under any current development and therefore there is some risk in that it will change or not ultimately be certified and offered).

Honeywell’s solution for VDR Upgrade to provide VDL M2 capabilityWith the implementation of the EUROCONTROL mandate, any airline operators flying within European Airspace
need to have VDL Mode 2 Data Link capability installed on VHF #3. Mix-ability between VDL Mode 0 and VDL Mode 2 units will vary depending upon aircraft platform and OEM. Honeywell’s VHF Data Radio (VDR) – Model RTA 44D and Integrated Primus EPIC Radios are upgradable to provide VDL M2 capability for all kinds of platforms supporting multi-frequency capabilities as per the European mandate A631-5/6 standards.
This conversion includes hardware and software modification that vary according to the serial number of the VHF. Honeywell’s plan is for two service shops to perform the relevant service bulletins (Seattle Area Service Center (SASC) and Toulouse Service Centers (FSC)).

Honeywell continues to lead the way in ATM technologies, developing MKII+ CMUs for future compliance with the anticipated changes to data link requirements including data link encryption. The hardware of part numbers 965-0758-005 (ARINC 724B version) and 965-0758-006 (ARINC 758 version) is designed to support the future data link requirements with only software upgrades necessary to achieve future functionality as per the table to the left. These technology roadmaps include three important upgrades linked to the PM CPDLC software: — The AOC function has been enhanced to supply greater customisation capabilities. — The ACARS Reconfiguration Tool (ART)
has been improved so that multiple elements of the AOC database (e.g. parameters, screens, downlinks) may be viewed and edited simultaneously.
— The Airsim tool has been upgraded to enable the simulation of the CPDLC function.
