This page shows the set of data link performance statistics at the level of the ATM Network (i.e. in principle all ANSPs but currently only Maastricht UAC and Skyguide are providing data) for all ATN equipped aircraft for May 2013. As the tool to create these metrics is still under test and validation not all the metrics are available yet. There is a corresponding set of graphs for FANS equipped aircraft and a further limited set of graphs that show the trend of these metrics over the preceding year.
Click on the graph to bring up a description of what the metric is measuring.
