Gothenburg City airport is leading the way in Sweden for satellite-based landing procedures enabled by Europe’s EGNOS system – improving accuracy and safety when aircraft land in a very cost effective way.
On 18 September 2014, Gothenburg City Airport became the first in Sweden to publish an EGNOS-based approach procedure. As a result, today runways 1 and 19 are operating LPV (Localiser Performance with Vertical Guidance) landing procedures.
“For the aircraft, the use of the new procedures will improve safety, increase capacity use, and save on costs over the long term,” says Annika Nyberg, CEO of Gothenburg City Airport.
LPV procedures are already in use in more than 114 airports across Europe, providing a cost effective alternative equivalent to conventional ILS CAT I instrument landing procedures. LPV offers similar performance without the need for significant on-site infrastructure installation and maintenance. For these reasons, it is becoming a very valuable navigation aid to small and medium-size airports, increasing safety and accessibility to those aerodromes.
Cost-effective and safe
Gothenburg City Airport was chosen for first implementation in a pilot case launched by GSA due to two aircraft operators showing interest in LPV procedures and several EGNOS-equipped aircraft already flying from the airport. In addition, it was an ideal location for a pilot implementation project.
Three operators at the airport have already implemented SBAS, and other aircraft are awaiting equipment upgrades to take advantage of LPV at the airport. In addition, helicopters are taking advantage of the procedures. A helicopter EGNOS survey conducted under a previous GSA-funded project raised awareness of LPV and PinS (Point in Space) procedures among the Swedish helicopter community. Two helicopter operators, Norrlansflyg ambulance and Scandinavian MediCopter, have already registered their interest in upgrading their aircraft to LPV capability.

GSA has previously undertaken a number of awareness projects in Sweden with airport authorities, aircraft operators and regulators, helping them understand the value of EGNOS and the challenges of implementing SBAS at high latitudes.
“LFV has done a great job in design, construction and implementation of new approach procedures,” says Karin Schagerlind, Head of Operations, LFV Air Traffic Services at Gothenburg City Airport. “With the right training we are now excited to start a procedure that will benefit aviation a great deal.”
LFV, the Swedish air navigation service provider, is currently working to publish LPV procedures at Sweden’s Storuman airport, also supported by GSA. LFV has final contracts with four further Swedish airports to start SBAS procedure design and implementation, and is also discussing offers with a number of other airports across the country.
EGNOS is Europe’s Satellite-based Augmentation System (SBAS) that can enable satellite navigation systems to meet the operational requirements set by the International Civil Aviation Organisation (ICAO) for the most critical phases of aircraft flight, in particular landing. The project to prepare the airport for LPV operations was funded by the European GNSS Agency (GSA) and implemented by Swedish air navigation service provider LFV.
