Efficiency (cont’d)
savings of between €50-70 million on an annual basis,
depending on the scenarios agreed.
Airspace users could make further savings by exploiting
to a greater extent the optimum routeings which are
made available to them, and more savings are expected
as a result of route availability and TMA improvements in
the future.
Sharing airspace more efficiently
Under the flexible use of airspace (FUA) concept, the
sky is seen as a single resource to be used according to
the needs of both military and commercial aviation on a
day-by-day basis. Freeing up airspace that was
previously reserved solely for military purposes allows
the implementation of conditional routes (CDRs) across
that airspace when it is not in use.
Analysis undertaken between 10 and 14 September 2007
revealed that over this five-day period 198 segments of
airspace were made available for 142 CDRs, indicating
an availability of 65% of CDR2 (non-permanently plannable)
and CDR1 (permanently plannable)/CDR2 routes.
On these routes, flight plans for 108 segments (55%)
were submitted by 54% of the potential users. Finally,
two thirds (approximately 68%) of users, submitting flight
plans for CDR routes, actually flew those routes. For this
particular week, 2,945 flights saved 463 tonnes of fuel
(the equivalent of 1,461 tonnes of CO2 emissions), but if
all CDRs had been fully used, another 5,340 flights could
have saved 445 tonnes of fuel (or the equivalent of 1,399
tonnes of CO2 emissions).
More efficient civil-military coordination
The Agency made progress in the review of the military
key performance areas, performance indicators and targets
with the aim of developing a civil-military performance
framework, which will ensure appropriate measurements
and changes in line with the SES/SESAR developments.
The Pan-European Repository of Information Supporting
Military Key Performance Indicators (PRISMIL) programme
will automate the collection of ATM data required
to produce military key performance indicators through-
Collaborating on efficiency gains
2007 was an extremely busy year for EUROCONTROL
in terms of network efficiency improvements.
Improving flight efficiency through airspace
design and management
Flight-efficiency is a major ATM performance issue. The
Performance Review Commission has estimated the
impact of non-optimum routeings to be at €2.4 billion
in 2007.
Throughout the year, the Agency continued working to
progressively reduce route extension per flight by 2 km
each year until 2010. Current assessments indicate a
minor improvement to flight efficiency in 2007. This
should be seen in the wider context of high traffic
growth, reduced capacity due to staffing problems and
adverse weather conditions.
Analysis carried out for the first week of September
2007 highlighted where route extension efficiency gains
had been achieved. An examination of flight plan data
confirmed that there was a slight reduction in flight
extension particularly for flights longer than 300 nm.
However, on average, flights under that distance
experienced some degree of flight extension increase
as a result of tactical trade-offs between capacity and
efficiency measures.
In November 2007, the Provisional Council approved an
Airspace Action Plan outlining concrete pan-European
actions to improve network efficiency and capacity and
reduce fragmentation. When implemented in full, the plan
has the potential to significantly improve flight efficiency,
albeit in a gradual manner. ATS route network ARN V6
would, for example, generate savings in the order of
60,000 nautical miles (nm) in a day, equating to about
€250 million a year. Full deployment of the ‘Advanced
Airspace Scheme’ would generate further savings of
30,000 nm a day – equivalent to approximately €150
million every year. In addition, the implementation of
flight-efficiency scenarios could produce savings of as
much as 15,000 to 20,000 nm a day, resulting in overall
41
out Europe. In 2007, a demonstrator was developed
which proved the concept, the proposed technology
and its architecture, and following that, the programme
development phase was initiated. Moreover, PRISMIL
coverage was extended to include new participating
Member States.
In 2007 the Agency continued to develop an airspace
management supporting tool for the enhancement of civilmilitary
coordination and improved airspace management
performance at national and European levels. The concept
description and specifications have been finalised and the
