service providers, civil and military
aviation authorities, airlines, airports
and EUROCONTROL worked closely
together to improve the performance
of the European air traffic management
(ATM) network. Between 1999 and 2008,
while traffic grew 27%, the capacity of
the network increased by 47% reducing
total en-route ATFM delays by 66%. In
parallel, routes flown were shortened
by an average of approximately 5 km.
Together these improvements generated
3.5 million tonnes of CO2 savings per
year. Currently, the European ATS route
network is only 3.5% longer than the
great-circle distances (for intra-European
flights).
Major challenges ahead
The European Community’s Single
European Sky (SES) legislation identifies,
in Article 6.1 of the SES Airspace
Regulation, the need for “route and sector
design to ensure the safe, economically
efficient and environmentally friendly use
of airspace”.
To ensure a continuously improving
performance, the EUROCONTROL
Provisional Council adopted two important
operational performance targets for
the European ATM network:
n a flight efficiency target that requires
a reduction in the European average
route extension per flight of two kilometres
per annum until 2010 with
subsequent emissions reductions;
n a network average en-route delay
target of 1 minute per flight for the
summer season (May-October) till at
least 2013.
Future challenges in terms of capacity,
flight efficiency and environment are high.
The current financial crisis, the traffic
downturn, the evolution of oil prices and
environmental pressure require accelerated
action in the improvement of
European airspace. The existing plans
have the potential to respond to these
challenges.
A consolidated work
programme
In 1997, the EUROCONTROL
Provisional Council approved the
Airspace Action Plan and the Airspace
Management Improvement Initiative that
set concrete actions for the improvement
of European airspace design and
utilisation. In addition, EUROCONTROL
developed a Terminal Airspace
Improvement Initiative comprising a
comprehensive toolbox of operational
improvements.
During summer 2008, IATA, CANSO
and EUROCONTROL agreed to work
in an even closer partnership along
with airlines, airports and air navigation
service providers (ANSPs) to
identify solutions and launch operational
actions that will lead to fuel and
emissions savings in the short term.
This resulted in the development of a
common Flight Efficiency Plan that was
built on the solid foundations of current
work undertaken by the air navigation

service providers, States, airports and
EUROCONTROL to improve European
airspace design and network management
and was in line with the common
objective of a Single European Sky.
A partnership approach
At European ATM network level, all
airspace design actions are consolidated
through the work of the EUROCONTROL
Airspace and Navigation Team (ANT)
and its specialised Route Network
Development Sub-Group (RNDSG). The
RNDSG is the coordination forum for
European rolling airspace design and
development, planning and implementation
of the improved European ATS
route network, optimised civil and military
airspace structures and ATC sectors.
The RNDSG is a group through which
civil and military experts representing 43
States and their ANSPs, eight international
organisations, including airspace
user organisations and EUROCONTROL
work in partnership to constantly improve
European airspace design and utilisation.
The ANT’s RNDSG develops agreed
pan-European solutions demonstrating
the commitment of the aviation industry
to work together to address significant
operational, economic and environmental
challenges. The Director
Operations of the European ANSPs
are directly involved in monitoring the
implementation of these European ATM
network operational improvements
through the EUROCONTROL Operations
Coordination Group.
A long-term vision
The RNDSG developed a long-term
vision of the European airspace structure
called the Advanced Airspace Scheme
(AAS) Route Network. The AAS Route
Network is based on the AAS operational
concept and the DMEAN operational
concept and integrates airspace design,
advanced airspace management/FUA
and ATFCM.
The AAS Route Network constitutes
