HFDL Overview


HFDL has been available to the airlines for over a decade and in that time usage has grown by an average of 20 per cent a year.

More than 85 airlines with 2600+ aircraft equipped send 4.8 million messages a month. Growing numbers of new aircraft are being built with HFDL available as an option, and more airlines than ever are specifying it.

Along with VHF and satcoms, HFDL is part of the Rockwell Collins GLOBALink portfolio of services that provides access to industry-standard ACARS air-to-ground data communications. Rockwell Collins ARINC was the first to offer HFDL service, and is still the only provider with global coverage - and that’s one of the great strengths of this technology.

VHF datalink is very effective over line-of-sight ranges in continental airspace. But it’s physically impossible to emplace the relay stations on the oceans or in wildernesses like the poles and Siberia.

Geostationary satellite systems provide round-the-world coverage but can’t reach the poles. Low-Earth-orbit satellites overfly the poles but the system has yet to win broad air transport industry acceptance. Only HFDL can offer a combination of global coverage and a significant installed base.
