Airport
operational
stakeholders have
to have a framework,
of course, under which
they can jointly manage the
environmental impact of air traffic operations
at and in the vicinity of an airport.
EUROCONTROL is therefore encouraging
these groups to consider adopting
Collaborative Environmental Management
(CEM) ?
a strategic process for operational
stakeholders to establish an airport
environmental partnership. Implementation
guidance should be approved by stakeholders
before the end of 2008. Many
airports already have something like this
in place; they tend to be among the best
when it comes to environmental practice.
CEM is a key SESAR enabler and the
SESAR ATM Master Plan requires that it is
widespread practice by 2013.
Another aim of the Flight Efficiency Plan
is to raise awareness among airspace
users, air navigation service providers
and EUROCONTROL on how to save
fuel and reduce emissions. Specific
training material will be developed for
this, and will expand the suite of environmental
awareness products available
through EUROCONTROL. Starting with
揈nvironment in ATM?e-learning in 2006,
the Agency now offers a five-day in-depth
classroom training course for ATM professionals
that is already oversubscribed.
By the end of 2009, over 100 ECAC
ATM personnel should have completed
this course. In addition, subject-specific
training is already available on the environmental
aspects of Airside Capacity
Enhancement. Training will be expanded
to cover CDA, performance indicators
and impact assessment over the next
two years. The forthcoming review
period of the Common Core
Content for Air Traffic Control
Officers provides the opportunity to
include a new module on environment
issues for instruction from 2012.
It is increasingly clear that the successors
to the A320 and B737 aircraft are at least
a decade away. Incremental improvements
in environmental performance
through fleet turnover will therefore be the
norm. Despite current economic problems,
traffic should still grow at between
2-4% annually over the next decade.
So, ATM has before it about a ten-year
period during which its aviation sector
partners will expect it to deliver a network
that decreases environmental impact per
flight and allows new production aircraft to
achieve their maximum possible environmental
performance.
The short- to medium-term actions to
improve gate-to-gate flight efficiency
include Collaborative Decision Making at
airports, Flexible Use of Airspace within the
Dynamic Management of the European
ATM Network (DMEAN) programme and
the vital work to adjust routes as part of
a continuous process of network improvements.
Altogether, we estimate that
these, together with CDA implementation
at about 30% of the ECAC airports,
should deliver annual fuel savings of over
600,000 tonnes annually, thereby avoiding
the emission of 2 million tonnes of CO2.
In addition, the use of aircraft and ATC
system capabilities to their full potential
should allow us to improve departure
track keeping for noise management
purposes, increase the height at which
CDAs commence and introduce CDAs
into busier and busier airports over time
without constraining capacity.
The major infrastructural development
that should further reduce fuel burn and
emissions per flight is of course the implementation
of Functional Airspace Blocks
(FABs) as required under the Single Sky
legislation. The airspace optimisation
delivered by FABs should further reduce
route lengths, fuel burn and emissions.
In addition, they should also provide the
opportunity for airspace optimisation
around airports which could facilitate
more CDAs from higher up the descent
path. Robust, harmonised assessments
of these changes will deliver a consistent
set of facts and figures with which to
demonstrate the environmental difference
that ATM can make.
Finally, working in partnership in SESAR,
all ATM stakeholders have the opportunity
to develop and deploy the post-2020 ATM
system mentioned above: the one that
allows aircraft to fly at maximum environmental
efficiency. With that successfully
accomplished, ATM will have seized its
