Abstract:	The most important objective behind the utilization of the EGNOS system in aviation is the achievement of a complete operational implementation in all phases of flight, especially in the approach phase, where the main objective is to perform RNAV GNSS approaches down LPV minima. Most efforts are focused on promoting the adoption of EGNOS by interested end users of identified niche markets. Therefore, the main activities in Europe have focused so far on regional airlines, business and general aviation, as well as helicopter operators. Aiming at supporting the introduction of EGNOS and Galileo services in the aviation market, the first GIANT project targeting the "GNSS Introduction in the Aviation Sector" was born in 2005 and ended successfully in October 2008. The Project main objective was to show economic and operational benefits to end users while demonstrating to the responsible authorities that the required safety levels are maintained or improved. The project (www.gnss-giant.com) paid special attention to how GNSS systems particularly meet the needs of regional airlines and helicopter operators and special effort within the project was devoted to the Flight Demonstrations in two of these domains. It successfully promoted and trialled the introduction of EGNOS-based LPV applications in the area of Regional Aviation, helicopter HEMS (Medical) operations and North Sea Oil Rigs operations, with special emphasis and effort devoted to the flight demonstrations with the Bombardier CRJ200 with integrated Rockwell Collins avionics. After the successful completion of the GIANT Project, the European GNSS Supervisory Authority (GSA) awarded a second contract (GIANT-2 Project, http://giant2.ineco.es/) under the first Call of the Galileo 7th Framework Programme, for the continuation of these EGNOS-based LPV approaches activities in other three key identified niche markets: Business Aviation, General Aviation and SAR Helicopters, with special focus and effort devoted to the flight demonstrations with Dassault Aviation Falcon 2000 with Rockwell Collins equipment and Cessna 172 with Garmin avionics in different scenarios in Europe. Therefore, EGNOS-based LPV approach demonstrations and related technical support studies and analyses are being performed in different projects and benefits have been demonstrated for the key interested markets in Europe. The next steps and coming projects supported by the European Commission and Eurocontrol are aiming at starting a European wide-scale real-life adoption of EGNOS and GNSS in aviation, facilitating, fostering and providing support to airlines, end users for aircraft equipage, as well as ANSPs and airports for the publication of LPV procedures.
