Rapport Annuel 2025 - Efficacité - Ponctualité en route: fluidité et efficacité

Reducing the en-route delay demonstrates that air traffic is fluid and organised efficiently.

This is the en-route punctuality performance target included in the FABEC performance plan for the 4th reference period. This is the target for skeyes and represents its contribution to both FABEC and European network performance. This indicator takes into account all causes of delay, such as weather, not just those that skeyes can control (CRSTMP).

skeyes’ actual en-route punctuality performance for all causes. This was the best performance in FABEC. Target achieved for skeyes, which contributed positively to the performance of FABEC (Belgium, Netherlands, Luxembourg, Germany, France and Switzerland) in terms of punctuality.

Retard ATFM en route moyen par vol dans l’espace aérien du FABEC toutes causes confondues. En 2025, le FABEC n’a pas atteint son objectif de limiter le retard en route toutes causes confondues dans son espace aérien fixé à 0,63 minute par vol. Néanmoins, le FABEC a pu maîtriser le retard généré par l’ATM dans son espace aérien puisqu’il a été réduit de 0,02 minutes par vol par rapport à 2024, après une forte diminution de 0,46 minutes par vol cette même année. L’amélioration est notable dans un contexte d’augmentation du trafic. Le FABEC regroupe 6 États (Allemagne, Belgique, France, Luxembourg, Pays-Bas et Suisse) et gère plus de 55% du trafic aérien européen. La performance de skeyes en matière de ponctualité en route a contribué à réduire le retard moyen en route dans le FABEC.

skeyes delivers FABEC's best performance in en-route punctuality.

3.0 seconds of average en-route delay per flight (CRSTMP causes)

skeyes’ actual en-route punctuality performance taking into account only the causes that skeyes can control (CRSTMP). This is an improvement of 0.01 minutes per flight compared to 2024, or 0.6 seconds.

The relative importance of the weather factor in the en-route delay has increased tenfold in 25 years. As a marginal factor in 2000, it accounts in recent years for more than a quarter of the causes of en-route delay. A tangible sign of climate change and the proliferation of extreme weather events.
