The declaration of the EGNOS Safety of Life service in March 2011 marked the moment when satellite navigation became certified for safety-critical aviation operations in Europe, allowing pilots to rely on EGNOS for precision approaches and improved situational awareness during landing.  Fifteen years later, the service continues to play a critical role in improving safety, accessibility and efficiency in European airspace, demonstrating the long-term value of satellite-based navigation for safety-critical transport applications.
