EGNOS has reached an impressive milestone with 1,000 approach procedures now utilising its Satellite-Based Augmentation System (SBAS). This achievement highlights EGNOS's vital role in transforming aviation safety, accessibility, and sustainability across Europe.
Supporting safety in aviation
The integration of EGNOS has introduced Localiser Performance with Vertical Guidance (LPV) procedures, a significant advancement in navigation technology. LPV approaches are praised for their precision and safety. As a representative from NetJets remarked, “LPV with EGNOS provided a big leap forward in terms of the minima and level of safety provided by GNSS approaches, without the need for additional ground infrastructure.”
Unlike standard GNSS approaches, LPV procedures are unaffected by low temperatures or incorrect altimetre settings, offering greater accuracy and reliability. They also enable smaller aerodromes to achieve approach minima comparable to an Instrument Landing System (ILS) without the need for costly installations. Additionally, LPV maintains operational continuity at larger airports when an ILS is inoperative. “LPV gives a greater degree of accuracy when compared to a standard GNSS approach, giving lower minima. It also improves safety as the glidepath is not affected by low temperature or incorrect altimeter settings, which can impact standard GNSS approaches.”
Building for the Future
As the adoption of EGNOS expands, operators are aligning their fleets with this cutting-edge technology. An Air France spokesperson noted, “Every new unit must have SBAS implemented so that LPV procedures can be performed.” This commitment ensures that airlines are equipped to maximise the benefits of EGNOS-enabled approaches, from improved precision to enhanced operational efficiency.
The growing number of LPV procedures also reflects a shift in how the aviation industry values this technology. An Air Nostrum representative recalled the early days of EGNOS adoption, stating, “Now, with around 1,000 EGNOS-based procedures, it is easy to find the usefulness of an LPV-equipped aircraft, but back then, it was a gamble at the time.” They added, “With the increase in LPV procedures available at European airports in the latest years, they have been benefitting from the advantages of LPV in the recent years.”
A More Sustainable Aviation Sector
In addition to its operational benefits, EGNOS contributes significantly to environmental sustainability. By ensuring greater flight path visibility, EGNOS procedures reduce fuel consumption and carbon emissions. According to some estimates, optimised flight routes and shortened flying times can save at least 100 kg of CO2 per flight, while landing using a continuous descent into an airport can save at least 150kg of CO2 per flight.
Transforming Aviation
The growing adoption of EGNOS and LPV procedures has made cutting-edge navigation technology more accessible and sustainable for large and small aerodromes alike.
As EGNOS surpasses 1,000 procedures, its role in shaping the future of European aviation is undeniable. With proven benefits for safety, sustainability, and operational resilience, EGNOS continues to be a cornerstone of modern aviation.
“At EUSPA, we are proud to have contributed to these significant advancements. By enhancing safety and efficiency in the aviation sector, we are helping to create a more reliable and sustainable future for all stakeholders involved,” confirmed Jean Marc Piéplu, EUSPA Head of EGNOS Exploitation Department.
