For more than 50 years airports have relied on instrument landing systems (ILS) to provide pilots with approach and landing guidance in low-visibility conditions, such as heavy rain and low cloud. Although the system has proved to be reliable and functional, ILS is costly to maintain and has operational limitations that reduce runway capacity in certain conditions. It is no surprise then that airports are turning to other solutions, such as ground-based augmentation of satellite navigation systems (GBAS), to meet their capacity needs and reduce delays and disruptions for airspace users and passengers.

This solution is planned for implementation in at least 11 airports in 7 Member States: Germany, Spain, France, Italy, Poland, Portugal, and Sweden.

Benefits

-Improved resilience by limiting the capacity reduction in degraded situations and by avoiding critical and sensitive areas)
-Reduced installation and maintenance costs compared to ILS
-Maintained level of safety
-Greater frequency efficiency
-Improved environmental impact due to shorter routes and noise abatement
