follow-on work was launched at the start
of 2007, aimed at delivering short-term,
quick-win solutions to current airport
issues under the leadership of programme
manager Eric Miart. He explains: “We are
implementing existing solutions such as
Air Traffic Control (ATC) procedures,
Airport Collaborative Decision Making
(A-CDM), and Surface Movement
Guidance and Control Systems
(SMGCS).” The programme is closely
allied with the objectives of the Dynamic
Management of the European Airspace
Network (DMEAN) programme, including
closer integration of airports in the ATM
network, and improved runway safety.
A-CDM is one of six projects in the
programme, with early results showing
gains in capacity, efficiency and
environmental cost.
“We have already implemented best
practices and CDM at three on the list of
25,” says Miart. Two years into a
programme to introduce A-CDM, Lisbon,
Prague and Brussels airports report
financial benefits. “We have just started
projects at London Heathrow and Paris
Charles de Gaulle, where we expect to see
similar results by 2011.”
In June 2007, Munich became the first
airport to operate a fully collaborative
programme, involving the airport, airlines,
ground handlers and air traffic control.
The programme has led to reduced taxi
times, and fuel savings worth a2.65
million per year (and 18,700 tonnes of
CO2) as a result of A-CDM measures
introduced over one year. “If you were to
have A-CDM implemented at the top 20-
25 airports that generate the maximum
delays, I think the benefits would be
enormous in terms of percentage delay
reduction, like at Munich,” says Miart.
Head of apron control at Munich, Peter
Kanzler, says the airport began

Europe’s top 25
airports are where
80 per cent of
airport delays occur.
They are at the
point where multiple
players from all
sectors of the
industry come
together in a
complex mix
collaborating with stakeholders in the late
1990s. “Our focus was runway capacity
where, in winter, de-icing operations
contribute to bottlenecks. We put the
right people together around the table at
the right time. We all had the same idea.”
Munich followed EUROCONTROL
guidelines and developed procedures to
share data between all the partners.
Matching flight-plan information,
comparing times and data from different
sources was a crucial part of the process.
Kanzler says the information is now much
more precise, and as a result the airport
handles its resources much more efficiently
than before. Munich has succeeded in
reducing delays during 2007, despite a
5 per cent rise in traffic.
The impact is more widespread than
just at the airport itself. Munich sends
Departure Planning Information (DPI)
messages to the Central Flow Management
Unit (CFMU) that manages traffic flow in
Europe’s upper airspace. The data provides
the CFMU with more accurate take-offtimes
two to three hours before departure.
At 25 minutes before take-off, the
accuracy of a predicted take-off based on
flight plan data is between 9-18 minutes.
This falls to between 7-12 minutes when
DPI messages are used, enabling the
CFMU to optimise the existing ATM
network capacity. Zurich and Brussels
anticipate using similar messages by 2008.
EUROCONTROL published an
A-CDM cost benefit analysis in late 2007,
using data from participating airports:
Barcelona, Brussels, Munich and Zurich.
It calculates that a generic airport model,
handling 280,000 movements a year, with
average delays of ten minutes per
movement and operational costs of a370
million, could realise savings of a6 million
within two years, rising to a14 million in
three years. It estimates investment by the
airport, ground handlers, airlines and ATC
of less than a10 million would realise
savings of a90 million over a ten-year
period – a cost benefit ratio of nine.
The analysis concludes there is “a
compelling case for all partners to
implement A-CDM as a very cost effective
operational efficiency enabler.” It adds: “ACDM
has the potential to save tens of
millions of euros and reduce CO2 emissions
by tens of thousands of tonnes per annum.”
