The Airbus A350 XWB recently became the first wide-body jet to achieve certification for its installed EGNOS-based landing system – a significant step in the uptake of the service within the commercial aviation sector.

EGNOS is fully integrated into a common, harmonised landing system interface on the A350 – the SLS. This allows the pilot to fly precision approaches similar to an Instrument Landing System (ILS) with geometrical vertical guidance down to the same minimum decision height as for CAT I operations. This new navigation system provides Airbus operators a wider range of solutions to optimise operations and increase accessibility without compromising on safety.

The EGNOS-enabled Airbus 350 XWB was recently on display during the EGNOS Flight Demonstration, held in Toulouse, Airbus’ home base. “As a test pilot, I had the opportunity very early on to perform Localizer Performance with Vertical guidance, or LPV, approaches based on the EGNOS constellation on the A350 XWB,” says Airbus Test Pilot Jean-Christophe Lair. “Overall, my experience on using an LPV EGNOS approach system is fully satisfying!”

Growing Demand

Today, 150 airports in 18 countries across Europe have EGNOS approaches implemented. Besides three geostationary satellites, the network uses 40 ground stations, allowing for precision guidance and safety. More so, there are currently 256 EGNOS-based approach procedures (LPV and EGNOS enabled Baro) and, by 2020, this number is expected to double.

Having met the performance standards set by the International Civil Aviation Organization, EGNOS is a proven, cost-effective way for both large and small airports to expand their navigation infrastructure and increase aircraft safety.
