Data

Everything behind the charts, for the ECAC area over 2026-01-01 → 2026-07-20. Type to filter by airport name or ICAO code — the tables narrow as you type. Column headings are dotted: each one is defined in the glossary.

Routes furthest from the norm

Δ norm in points against flights of the same length and type. Rankings use only routes with at least 100 flights. ⚑ = the direct path crosses closed or avoided airspace (208 routes flagged).

Airports furthest from the norm

Arrivals and departures combined, at least 2,000 flights.

What this table does not say. Each row measures the modelled deviation of the flights that touch an airport. It is not a measure of that airport's performance, of its responsibility, or of emissions it could avoid, and it does not establish that the airport caused anything.

A high value may reflect operator choices, air traffic control constraints, congestion, the structure of the surrounding airspace, aircraft type, weather, or other factors this analysis does not separate. The flight is counted at both of its ends. The fuller note is on the home page.
