Context

Performance review for all ANS in EUROCONTROL Member States (41 + 2) EU-US comparison International Studies (Brasil, China, Japan, Singapore) Flown Flight Trajectories are input for our indicators: Traffic counts (Country FIR & ANSP, ACC, ...) Horizontal Flight Efficiency Vertical Flight Efficiency (en-route, climb & descent) Additional ASMA time Traffic Complexity

Principles

Impartiality

We do not serve any vested interest.

Transparency

We are open to scrutiny and willing to collaborate.

SLIDE 4

Principles' Consequences

Reproducibility

slide-5
SLIDE 5

If it ain't openly reproducible don't call it performance review

...or research ...or science
