Leading Providers of CPDLC for Commercial AviationAs a part of the Single European Skies ATM Research (SESAR) joint undertaking, the Iris Precursor Programme phase one completion takes Europe another step closer to its goal of creating the worlds most advanced air traffic management infrastructure.

Now, with phase one completed, another €7.6 million of funding will now be made available by the European Space Agency (ESA) and its partners to commence phase two, which will focus on the satellite network overlay.

ESA’s Iris Precursor Programme is operating in partnership with Inmarsat, the well-known British satellite company and will provide the means to streamline the current ATM system and allow aircraft to use Controller-Pilot Data Link Communications (CPDLC) to its maximum efficiency, increasing safety significantly over Europe.

Honeywell have introduced a new software upgrade that promises to double inflight connectivity speeds using Inmarsat’s SwiftBroadband service.

Honeywell expect it to be a ‘very popular upgrade’ which will also support current requirements and future mandates for safety, such as CPDLC and FANS, saving fuel and increasing safety as pilots are enabled to fly preferred routes.

Providers of Aviation Data Link Communications SolutionsAn Oceanic Data Link (ODL) service will be provided by Rockwell Collins to enable real-time data communications between ATC and pilots in a seven-year contract awarded by the FAA this week.

The ARINC data link service will be established in the FAA control centres in New York, Oakland and Anchorage under the contract, which will enable the air traffic control centres to conduct standard procedures on Future Air Navigation System (FANS) equipped aircraft. FAA aircraft tracking will be made possible while out of radar range.

Rockwell Collins currently works in conjunction with the FAA for the Next Generation Air Transport System (NextGen) initiative, providing voice and domestic data link.

Find Out More About CPDLCThe much-anticipated decision to move the CPDLC mandate deadline has been announced this week by the European Commission (EC). The new deadline will now be February 2020 for operators to equip their aircraft with Controller-Pilot Datalink Communications (CPDLC).

In a statement to Avionics magazine, Gzim Ocakolu, EC Directorate for Mobility & Transport policy officer said, “I can indeed confirm to you some recent important developments related to the implementation of Regulation (EC) No 29/2009.”

The news is welcomed across the industry following concerns regarding the technical issues related to the radio frequency environment and the infrastructure of the ground-based operations currently in place. It is these issues, discovered during an EC investigation into the implementation of DLS ground infrastructure, that have led to the delay for mandatory CPDLC installation, which would have been activated last month.

“Certain air navigation service providers have already taken mitigation measures, consisting of the restriction of DLS operations to aircraft equipped with specific avionics through so-called ‘white lists,’ so as to address potential safety impacts of those PAs in the operations of data link service,” the EC said.

Just 40% of operators would have been ready for the mandate, the investigation found, and only 70% of the necessary ground infrastructure would’ve been ready and fit for use. The implementation of CPDLC is critical to European airspace, with voice channels that have become heavily congested. Compliance will involve retrofitting aircraft with FANS, 1/A router, antenna, CPDLC interface and VHF Data Link Mode 2 radio (VDLM2).

More Information about CPDLC NextGen BenefitsThe FAA’s Bruce DeCleene will be a keynote speaker at the Avionics for NextGen 2015 conference later this year, opening the discussions about the modernisation of the National Airspace System.

The two-day conference, set for October 14 and 15 will open with Mr DeCleene’s discussion about the FAA’s progress with the implementation of major flight technology projects for the benefit of the aviation community as a whole.

Four initiatives are to be targeted over the next two to three years:

  • Datacomm
  • Performance Based Navigation (PBN)
  • Multiple runway operations
  • Surface & data sharing

Also open for discussion at the conference will be the ability of a range of different aircraft types to use existing infrastructure to implement next generation communications initiatives, such as CPDLC, and the ADS-B network in addition to discussions regarding Optimised Profile Descents (OPDs) and the wide area augmentation system.

The challenges associated with the provision of new procedural initiatives and the creation of increased peak throughput at the U.S.’ busiest airports, including re-categorisation of aircraft wake turbulence characteristics will be highlighted at the conference and attendees will hear from pilots and air traffic controllers about the advantages of Controller-Pilot Data Link Comms (CPDLC) and Required Navigation Performance (RNP) in terms of the improvisation of the use of national airspace, fuel cost savings and operational efficiencies.

It is hoped that many questions will be answered at the conference and operators will be assisted with their decision-making regarding the right investments to make for onboard technology to meet the objectives of the NextGen air transportation system.

Providers of CPDLC for Enhanced Operational MessagingThe transition to Controller-Pilot Data Link Communications (CPDLC), according to the original timeline, should by now be well under way, with retrofit requirements under the Single European Sky initiative due by next month.

The European Commission has indicated that the deadline will now be moved to make sure that the industry is ready and that CPDLC avionics are reliable. Air Navigation Service Providers (ANSPs) are implementing the infrastructure in advance of the mandates and the SES initiative is still a global reality.

Although the process is slow, and the costs for retrofitting high, the transition to CPDLC will save airlines and operators in the long-term and increase safety for the skies on a worldwide scale. It is unlikely that CPDLC will replace voice communications altogether, but datalink messaging needs to be implemented in order to cope with the upsurge in air traffic that is expected over the next two decades.

It is not just Europe that is attempting to embrace the CPDLC technology. Data link communications are being trialled in the U.S. under the NextGen program and in Canada, nationwide implementation of CPDLC was completed last summer.

Although phase two of the SES initiative was planned for next month, it seems likely that the plans, so far fraught with technical difficulties, training delays and the cost of retrofitting, may be moved as far as five years into the future.

A report has been submitted to IATA by the Aircraft Tracking Task Force (ATTF) this week, which will deliver its findings for consideration in the Global Aeronautical Distress and Safety System (GADSS) development.

Airline Operational Messaging Solutions ProvidersAlthough the contents of the report are not yet public, Tony Tyler, CEO of IATA said that the report ‘recommends that airlines evaluate their current tracking capabilities against the performance criteria and close any gaps within a 12 month time frame.”

According to Mr Tyler, airlines will need to complete phases in order to achieve complete, worldwide aircraft tracking capability:

Short-term – make use of the current capabilities within their fleets and operational areas

Near-term – look at the business case for upgrading equipment to meet performance criteria

Parallel – explore the possibility of making tamper-proof systems with other industry stakeholders and manufacturers

The recommendations included in the report encompass many improvements, particularly within the communications systems, such as Controller-pilot datalink communications (CPDLC) and ACARS to the space-based ADS-B, which, in the long-term is seen as the solution to seamless global aircraft tracking.

With mandatory equipage of these technologies fast approaching within European and Canadian airspace, new aircraft are already seeing these technologies coming as standard onboard installations.

For global tracking to become a certainty, technological capabilities must be installed and a ground-based ADS-B infrastructure is already in place.

“The public should be aware that there is no silver bullet solution on tracking,” said Tyler. “The industry is working to improve, but some issues such as tamper proofing, will take time to address and implement.”

Other CPDLC and HFDL Communications ProvidersThe Pakistan Civil Aviation Authority (PCAA) has signed a contract with M/s Wateen Telecom for the lease of managed services of Controller-Pilot Data Link Communications (CPDLC) via SITA’s network of voice and data solutions.

In a statement issued by the PCAA this week, the move is to ‘help radar controllers to establish a data and voice communication link from Karachi and Lahore on a 24/7 through 365 days basis.’

Using CPDLC and HF datalink communications, aircraft flying from any part of the world can communicate with the PCAA radar controller with an enhanced link that will improve the conventional VHF and HF wireless communications connectivity, particularly on long-haul flights.

The move comes as the PCAA strive to strengthen the Pakistan Airspace with CPDLC integration into the air traffic management system.

The use of CPDLC is gaining momentum as providers aim for the enhanced capabilities, reducing pilot and flight crew workload in commercial and business aircraft across the world. CPDLC can give flights access to faster routes, which can also help to manage costs in terms of fuel and airspeed, maximising operational productivity.

Rockwell Collins' FANS 1/A & CPDLC CapabilitiesIt has been announced that Rockwell Collins is to offer FANS 1/A with CPDLC capability to the Bombardier Challenger 604 aircraft currently equipped with their Pro Line 4 avionics systems. The upgrade will be made available in mid to late 2015 and will build upon the aircraft’s current Flight Management System (FMS) and Control Display Units (CDUs).

The incorporation of a new communications unit will give operators of the Challenger 604 access to the transatlantic route that offer greater wind-efficiency, which results in significant savings of both time and fuel for the carriers.

The FANS 1/A package is made up of Controller-Pilot Data Link Communications (CPDLC) capabilities and Automatic Dependant Surveillance-Contract (ADS-C) which offer both enhanced clarity for pilot communications and a reduction in flight crew workload.

Global SwiftBroadband Providers for Flight Deck CommunicationsL2 Consulting Services, avionics engineering, integration and installation services providers, have announced a contract from Cobham SATCOM to develop the STC for AVIATOR SwiftBroadband installations for Hawaiian Airlines 767-300 series aircraft. The certification will apply for the use of ACARS Ground Gateways (AGGWs) for FANS and ACARS safety messages.

With the design phase already in action, prototype installations and certification is on track for the projected completion deadline during the first quarter of next year.

President of L2, Mark Lebovitz said, “This FANS 1 Controller Pilot Data Link Communication and Automatic Dependent Surveillance Contract to implement over SwiftBroadband Safety Services certification project is intended to support the FAA’s initiative to evaluate communication technologies that are expected to be viable in meeting the needs of the aviation community. We are delighted that Cobham SATCOM has entrusted our company with such a significant program to support FANS Evaluation flight trials towards meeting ICAO GOLD RCP240 requirements for support of 30/30 NM operations.”

AVIATOR SwiftBroadband is capable of delivering voice and data communications in addition to the provision of other critical services, such as aircraft tracking data, support for Electronic Flight Bag (EFB) and Ethernet connectivity for devices such as the Aircraft Interface Devices (AIDs).
