23% of flights, but only 4% of total fuel burn in
Europe.
The average ATM fuel efficiency is estimated to be
close to 94%. This is good news but means that there is
limited scope for improvement from ANS.
Total ANS actionable CO2 are estimated to be around
6% of total aviation related emissions and account
therefore of some 0.2% of total CO2 emissions in
Europe. Due to inherent necessary (safety) and desired
(noise, capacity) limitations, the ANS actionable
inefficiencies cannot be reduced to zero.

The extension of the horizontal en-route flight path is the main component (3.6% of total fuel burn) followed
by delays in the terminal area (1.1% of total fuel burn).
Significant fuel efficiency improvements could be realised by optimising arrival flows into main airports. In
the short term, high priority should be given (1) to the optimisation of the route network and (2) to the
implementation of arrival managers at main airports. In the longer term (SESAR), the focus should move to a
more integrated management of the flight trajectory geared to optimising arrival time.
Noise and local air quality are major concerns of residents in the vicinity of major airports. The
implementation of local restrictions implies complex trade-offs between noise, emissions, capacity and safety
which need to take into account local specificities.
The implementation of Airport Collaborative Decision Making (CDM) at more European airports would help
to improve taxi efficiency and hence local air quality and improve the accuracy and timeliness of information
locally and at network level.
Cost-effectiveness

EXECUTIVE SUMMARY
EXECUTIVE SUMMARY PRR 2009

This achievement directly translates into “savings” of some €3 billion with respect to constant 2003 unit costs.
The positive traffic growth during the 2003-2008 period has greatly contributed to this achievement, along
with greater cost-effectiveness awareness among a majority of ANSPs.
According to benchmarking findings, the decrease in unit costs between 2004 and 2008 is mainly due to the
fact that support costs remained fairly constant while traffic increased by +17%. This is consistent with
expectations of scale effects in the provision of ATC services. A main part of support costs, which represent
70% of ATM/CNS provision costs, are generally fixed costs in the short and medium terms and are not
expected to change proportionally with traffic volumes.
However, 2008 marks the end of a positive business cycle for the European ANS system and en-route unit
costs are planned to sharply increase in 2009 and 2010. As a result, the Pan-European target adopted by the
Provisional Council in Nov. 2007 (-6% reduction of unit costs between 2008 and 2010) will not be met.
The economic downturn, which became apparent in summer 2008, has affected the aviation community
throughout 2009 with unprecedented severity, requiring greater flexibility on ANSPs and EUROCONTROL
to adjust to new unfavourable economic conditions. In this context, no doubt that the pressure to genuinely
improve cost-effectiveness is high on the agenda of airspace users’ expectations.
Several European ANSPs have revised their plans accordingly and implemented cost-containment measures
for 2009 and 2010. All the five largest States plan to decrease their en-route cost-base in 2009 or in 2010.
EUROCONTROL has decided to freeze its 2010 cost-base at 2008 levels. It is important that these planned
cost reductions materialise in order to minimise under-recoveries that will negatively impact airspace users
through higher charges in future years.
It is however important that the implementation of cost-containment measures does not contribute to
