1. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Track 1 Summary Performance metrics in target setting

2. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Scoping The boundaries of the ATM system or the aviation system need to be clearly defined when using metrics as they are strongly impacting on the interpretation of the metrics values.

3. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Exchange of views Commonality between US and Europe in evolving from technology, political push to top-down performance driven ATM developments. The process is evolving on both sides. Europe appears to be somewhat ahead in safety area. Many commonalities in both high level and low level metrics.

4. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Contradiction ? While we are trying to understand better the performance of the current system in order to allow better target setting and selection of improvements, there is also a limit to what we can do. Some decisions will always have to be taken on the basis of incomplete information / lacking metrics.

5. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Elaboration At the highest level there are safety capacity cost Metrics allow to explain the story of how aviation operates to society We have to elaborate down to a suite of metrics to characterise performance

6. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Target setting Need better target setting Safety:: taxonomy / vocabulary Different stakeholders will have different perspectives on targets set. We need to be precise in what we measure and analyse Adaptability to variation in demand and policy changes needs to be captured in metrics.

7. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Target setting Need to understand the drivers in the complex ATM context before setting targets. Target setting needs to start at the local level and be aggregated to the higher level Gate-to Gate approach - network wide versus local dominance and competition

8. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Use How to USE the metrics: What do we do with the metrics to take decisions. Careful to target our questions. Some decisions are already made without having the right metrics. use metrics within the scope they are developed for.

9. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Use Use of metrics for the longer term is different (more focussed on vision and policy) than for the shorter term (more about what is realistically achievable) Links between various levels of metrics needs to be maintained. Target trade-offs need to be carefully understood and documented. Safety will remain set separately.

10. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Understanding Need to be more specific on what changes otherwise every concept may look as good as we want it. Consensus and consistency at higher level needs to be worked down to the lower levels. Common definitions. We need to speak the same language. Detailed concepts are required to identify activities and associated metrics.

11. One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) Challenge Metrics are the means not the objective In the end it is all about changing the human performance in the system We are still reactive. Are we moving to be more pro-active We dont need to guess our future, we need to make our future
