Figure 60: Geographical distribution of most delay-generating ACCs
5.2.28 The responsibility to plan and to deliver the right level of capacity lies with ANSPs.
EUROCONTROL supports the European medium term capacity planning with a number
of tools, data sets and traffic scenarios. The resulting capacity plans are then published in
the Network Operations Plan (NOP). The next section compares actual and planned
performance for the most constraining ACCs in order to better understand the reasons for
the observed en-route capacity shortfalls.
ACC CAPACITY PLANNING
5.2.29 To ensure the required delivery of en-route capacity in the medium-term, capacity plans
are developed by the ANSPs for each ACC. Figure 61 compares actual traffic demand

and ATFM delays to the forecast levels in the Medium Term Capacity Plan15 for the 10
most en-route delay generating ACCs in 2009.
5.2.30 Zagreb is the only ACC which reported an increase in traffic which was not foreseen by
the traffic forecast. In all other ACCs traffic decrease in summer was even higher than
initially forecast.

5.2.31 Although traffic was lower than forecast, Warsaw, Nicosia, Zurich, Langen, and
Athinai/Macedonia performed worse than anticipated, but for different reasons. Nicosia,
Langen, Athens and Makedonia ACCs did not fulfil the commitments made in the
capacity plan in terms of configurations and sector opening schemes.

5.2.32 Figure 62 shows the en-route ATFM delays in the top 25 most delay generating en-route
ACCs by sector type in summer. The ATFM en-route delays originating from collapsed
sectors show a worrying increase between 2007 and 2009.
5.2.33 Zurich, Langen and Warsaw show en-route ATFM
delay due to elementary sectors. This indicates
structural limitations to be addressed to avoid
excessive delays when traffic growth resumes.
5.2.34 At all other ACCs, shortcomings in the planning
(recruitment, productivity projections, etc.) and
deployment (sector opening times, ATCO rating,
rostering, overtime regulation, etc.) of staff appear
to be the main reason for the observed high level of
en-route ATFM delays.
