Datalink Summer Performance Report - July 2025

Datalink Summer Performance Report - banner

As of July 2025, the European datalink network is demonstrating significant progress in both performance and resilience, building on the lessons learned from 2024.  This report highlights the progress that has been achieved through the collaborative ‘#ThinkNetwork’ strategy which focuses on three pillars: strengthening network performance, harmonising controller-pilot datalink communications (CPDLC) operations, and enhancing monitoring.

#ThinkNetwork has helped to produce a more stable environment, reflected in improved Key Performance Indicators compared to the previous year. The logon rate has increased to 60%, and the Provider Abort rate has been substantially reduced to 4.84 per 100 hours, indicating a more reliable service for flight crews and controllers. Tangible achievements, such as fixing long-standing cross-border issues and enhancing network redundancy to cover over 80% of all CPDLC traffic, have been key to this success. 

To support all aviation partners and maintain this positive momentum, a "Datalink One-Stop Shop" has been launched, providing centralised access to critical resources like CPDLC playbooks, guidance materials and the new Datalink Outage Management Charter. While progress is evident, continued stakeholder engagement is essential. All users are urged to prioritise correct and consistent logon procedures, adhere to the outage charter principles, use the available guidance and promptly report any issues. Continued collaboration will ensure the development of a more robust and reliable datalink system for Europe.
