TrueNorth has expanded its communications products with the release of its new DLU-vox datalink and voice Iridium satellite communications system, which combines datalink and flight deck safety services voice capabilities in a single box. 

The DLU-vox will be compliant with current and foreseeable TSO specifications, according to TrueNorth (Booth S80), which is a division of Satcom Direct. It also has the same dimensions and footprint of TrueNorth’s TSOed Data Link Unit (DLU), which is the only system currently TSOed by the FAA, Transport Canada and EASA for FANS over Iridium datalink communications. 

Designed for use on the flight deck, the DLU-vox can be used for datalink communications via ACARS, ADS-C (contract), and CPDLC (controller-pilot datalink communications), and it is compatible with a variety of multipurpose control and display units (MCDUs) and FMSs. The DLU-vox supports simultaneous voice and data transmissions through a dual-element Iridium antenna, according to TrueNorth, “allowing pilots to talk and use the text-based interface at the same time.” Enhanced voice quality enabled by the DLU-vox “contributes to safer flight operations by providing clearer voice than traditional HF radio,” the company explained.

“The DLU-vox is an important addition to our product portfolio,” said Chris Moore, chief commercial officer at Satcom Direct. “FANS-1/A capabilities offer clear operational and business benefits. Pairing DLU-vox with SD services, like our FlightDeck Freedom application, gives operators the ability to work more effectively, fly more efficient routes and reduce fuel costs; significant considerations that are important to both pilots and aircraft owners.”

“Our focus is to consistently improve the user experience, be it in the cabin or the flight deck,” said TrueNorth general manager Mark van Berkel. “Our new DLU-vox will allow operators to better manage their workload. Text-based contact with air traffic control reduces communication errors, and a channel of enhanced quality voice provides added flexibility. Both will help foster smooth flight operations.” 

Installation of FANS-capable equipment also enables aircraft operators to take advantage of the new digital clearance (DCL) capabilities now live at 55 U.S. airports with Tower Data Link Service (TDLS)-equipped facilities as well as upcoming en route data comm services.
