helping to reduce congestion at airports in the short and long term.
Airport capacity
enhancement in action
Although the financial turbulence in
2008/2009 had a drastic downgrading
effect on European traffic demand,
economic growth is forecast to resume in
2011, which will necessitate more flights
in the medium term. The 2008 Challenges
to Growth study confirmed that Europe
continues to face an airport capacity
crunch. The European aviation industry
will have to resolve major challenges, one
of the most important of which will be the
availability of airport capacity.
The Challenges to Growth study forecasts
that in the most likely scenario,
by 2030 airport capacity will lag behind
traffic demand by some 2.3 million IFR
flights, equivalent to 11% of European
traffic. Put differently, 170 million passengers
will be affected and 19 airports will
process 50% of all flights and will have to
operate at full capacity eight hours a day,
every day of the year. This would mean
that the disruption of operations at these
airports for any reason (weather, unforeseen
events) will severely affect the functioning
of the European air traffic network
as a whole.
Although there have been significant
improvements in airport capacity
compared to four years ago (previous
Challenges to Growth report), the
capacity challenge is still an important
issue, not least due to the uncertainty as
to whether the planned capacity improvements
will actually be delivered. In order
for EUROCONTROL to work with stakeholders
in managing airport capacity
on a network-wide basis, the following
elements need to be in place:

n Dedicated database allowing airports
to submit information on capacity
issues via a secure connection
(Community Observatory on Airport
Capacity).
n Reduction in network delays.
n Structured Capacity Enhancement
and Planning Initiatives (Airside
Capacity Enhancement methodology).
n Capacity enablers under development.
n Greater flexibility allowing account
to be taken of the nature of airport
operations.
Community Observatory
on Airport Capacity
The Community Observatory on Airport
Capacity was established on 4 November
2008. This consultative body addresses
airport capacity issues from a European
perspective, looking in particular at
ways of aligning airport capacity with
ATM capacity so as to avoid delays and
congestion. The Observatory will also
advise on the implementation of the
action plans for airport capacity, efficiency
and safety in Europe.
Three working groups have been
defined: Airport Capacity, Gate-to-Gate
and Intermodality. EUROCONTROL will
play an important role in this initiative
by leading the Airport Capacity working
group and by contributing to the two
others.
In support of the Observatory’s mission,
EUROCONTROL will bring its experience
within a number of systematic and
effective processes for air traffic management
capacity planning at European
level. The European Commission may
wish to extend this exercise to produce
a comprehensive inventory of European
airport capacity.
Experience, exchange of data and
best practice will be enhanced, and the
Observatory is a key forum for establishing
a pan-European vantage point and
assisting in developing the measures to
make optimum use of European airport
capacity.
Reduction in network
delays
The need to analyse, calculate and
subsequently enhance airport/airside
capacity in Europe is clear. Increased
demand for airport slots will not be met
and delays will continue to increase.
Therefore a prime objective is to reduce
the network level of delay. Nevertheless,
reduction of airport delays should not be
considered in isolation nor disassociated
from airside capacity issues in general
or the runway capacity enhancement
process in particular. Providing additional
runway capacity is a key determinant in
any airport delay reduction process.
However, there is little point in enhancing
capacity or efficiency without analysing
the real reasons for the delays. In order to
meet this requirement a structured initiative
has been established including major activities
such as the analysis of the reasons
for delays, delay reduction action plans
and Airside Capacity Enhancement and
Capacity Planning (ACE) action plans.
