Working together since 2014, NAVBLUE and Zurich International Airport have improved the capacity of the airport and optimized efficiency in CAT III conditions
Low visibility conditions constitute a major challenge to airports, as raised separation requirements reduce capacity and cause delays. Thanks to the implementation of advanced technology and the support of NAVBLUE , Zurich International Airport has been able to increase the number of movements in low visibility conditions by approximately 20%, starting in October 2016.
In order to ensure that aircraft landings in CAT III conditions continue to be effected at the highest safety levels, Zurich Airport and the Swiss Air Navigation Services Provider, Skyguide, have invested in optimised landing technologies by installing a new Instrument Landing System (ILS) 32 elements localizer antenna, supported by NAVBLUE’s Exact Landing Interference Simulation Environment ( ELISEby NAVBLUE) solution.
ELISEby NAVBLUE helps airport services to increase capacity, reduce holdings and increase safety in low visibility conditions. It also enables optimization of airside land usage, allowing buildings to be built on land previously deemed non-constructible without disrupting the facility’s ILS signal.
ELISEby NAVBLUE has modelled the Zurch airport’s environment with a high level of accuracy including ILS settings and ground relief and the geometry of disturbances on the ILS Signal in 3D. The state-of-the-art simulations have been built to ICAO standard tolerances.
With this new technology and modeling in place, Zurich International Airport has been approved by the Swiss Federal Office of Civil Aviation to reduce the separation of arriving aircraft in low visibility conditions to five nm in final instead of the traditional six nautical miles.
