The world of CNS infrastructure at your fingertips

Our goal is to provide a network-wide view of CNS infrastructure as part of the EUROCONTROL Network Manager function to “monitor the performance of the infrastructure relevant for the execution of the network functions”.

This new function spans ground and space-based navigation systems, datalink communications, airborne collision avoidance systems (ACAS), airborne altimetry, surveillance interrogators and avionics. By monitoring the performance of infrastructure, we ensure the smooth running of the network and try to predict issues and outages before they have a serious impact.

To shine some light on the scale and importance of the CNS infrastructure for the overall network performance our panel gives users quick insight into three key metrics:

1. Delay caused by CNS infrastructure
   For those interested in more details, we provide an evolution view with a  monthly breakdown this delay segment in minutes and as a percentage of total delay going back to 2018;
2. Annual cost to States
   Ever wondered how much all of this infrastructure costs – we have that answer for you for communication, navigation and surveillance with a three years backlog and four years forecast;
3. Single European Sky implementation progress
   We also showcase the progress States have made in their Single European Sky implementation commitment with a specific CNS infrastructure focus.

Below our three KPIs, we give our curious visitors seven interactive maps highlighting some of the monitoring work we do to improve network performance. These include monitoring of:

• Datalink deployment status - showing the status of controller-pilot datalink communications (CPDLC) deployment in Europe’s airspace;
• 8.33 kHz conversion rate - showing the percentage of voice frequencies converted to 8.33-kHz channel spacing for each European State;
• Maximum number of Mode S replies/second - the peaks in Mode S reply rates per minute recorded during test flights above FL300;
• ADS-B equipage density – comparing the proportion of flights equipped with ADS-B v2 with the total number of flights for a specific airspace
• Frequency congestion - showing the number of VHF voice channels available for a new control sector in each geographical location
• DME/DME redundancy - showing the number of valid DME pairs available for area navigation using DME/DME position updates at 9,500 feet;
• PBN procedures – the implementation status and plans for PBN final approach procedures with vertical guidance at European airports.

Along with a short explanation and the maps powered by data collected as part of our function, our dashboard links to other web pages to helps you gain additional insight into our specific services – for those who want to learn more.
