RUAG develops straightforward and economical solution for CPDLC over ATN for Embraer Legacy 600/650 in European-Airspace

RUAG MRO International has developed a streamlined solution for CPDLC in Eurocontrol airspace on behalf of their business aviation customers flying with Embraer Legacy 600/650. The solution is a minor modification that builds on the OEM’s Service Bulletin (SB) for FANS / CPDLC. Using ATN by means of VHF, the modification supports a clear and prompt digital dialog between air traffic control and the cockpit. ...

The upgrade kit is available from RUAG’s business aircraft engineering and MRO team at Munich-Oberpfaffenhofen, Germany.

Embraer Legacy 600/650 operators are free to decide if they prefer to opt for CPDLC as outlined by Mandate 2020 from both the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA). “Our ATN-assisted modification package is purpose-designed to be straightforward and economical, requiring a downtime of five days for implementation. We believe this is a significant step towards making CPDLC technology accessible to a broad scope of Embraer Legacy operators, also in the Eurocontrol area,” states Christian Karl, Head of Sales Business Jets, RUAG MRO International.

Currently, those aircraft implementing CPDLC benefit from reduced voice-messaging requirements, improved communications accuracy, cumulative advantages from operations maintained above FL285, and optimum routing. “This is all about enhancing convenience for our customers. Installing this mod is similar to having a second SIM card on your mobile phone for receiving text messages in Europe, as well. Even if it is not mandated, it ensures you are best served, especially on busy routes or airports,” he explains. ATN-over-VHF is the designated technology for the Eurocontrol area.

Available as a kit, the upgrade includes approved data and required equipment. A precondition is Embraer’s FANS / CPDLC SB. CPDLC enables text messaging from air traffic control to the cockpit, ensuring communications remain clear and understood. Air traffic control for both EASA and FAA airspace prefer this method of communication as it safeguards clarity over the traditional spoken language method.  

The modification is also specifically developed to encourage those customers flying Embraer Legacy 600/650 to consider the technology necessary for the continued reliability and prioritization of communications within controlled airspace. “Ultimately, clear and precise communications enhance air traffic safety,” continues Christian Karl. “Implementation of CPDLC is a step forward in this respect and has the added benefit of permitting operators of these aircraft to take advantage of the time- and cost-saving assistance the digitalizing technology makes available.”

 “Our engineering team has created a solution that fulfills safety and compliance guidelines and then goes even further to allow our customers to take full advantage of a future-oriented technology in an economically sustainable approach,” confirms Volker Wallrodt, Senior Vice President Business Jets, Military & Dornier 228, RUAG MRO International. RUAG also recommends implementing the modification during the aircraft’s next  maintenance, repair, and overhaul (MRO) visit for optimized timing and further savings. If required for operations, RUAG is also able to provide a solution for PM-CPDLC (Protected Mode CPDLC).
