during the 2004-2005 winter season:
仭 Systematic debriefing of critical event situations
with some airports (well advanced with London
Heathrow, and in progress for Paris Charles de
Gaulle and Amsterdam Schipol)
仭 More flexible management of departure or
arrival regulation during an airport critical event
through slot swapping procedures
仭 Assessment of the current ATFCM procedures
with airports in the context of airport CDM

planning pays off
Extensive planning and training took place
prior to the Games, held in Athens during
August. Training was given to Aircraft
Operators (AOs) and ANSPs, comprising traditional
classroom teaching and distance
learning using Internet technology. The
CFMU received very positive and enthusiastic
endorsement of this approach.
During the Games an operator from Athens
ACC joined the CFMU/Flow Management
operations room to facilitate coordination
between the CFMU and Athens. Daily
e-conferences were held from 10 August to
31 August between the CFMU and Athens,
Tirana, Belgrade, Brindisi, and Rome ACCs.
Daily e-mail reports were also exchanged
with Cairo, the former Yugoslav Republic of
Macedonia, Bulgaria, Malta and Turkey.
There was considerable cooperation from
all the major players, leading to increased
flexibility in capacities, configurations and
routing scenarios.The result was that there
was no negative ATFM impact.
CFMU clients connect
The CFMU乫s clients, primarily aircraft operators,
airport handling agencies and ANSPs, can access
CFMU systems either via the Internet or a dedicated
network. The number is constantly increasing
and during the year 1,200 clients had accessed
the CFMU 2,948 times. This is due in particular to
the introduction of ETFMS and the associated
increase in accuracy of real-time data. The suite of
services available to CFMU customers has been
enhanced. The networking infrastructure has been
significantly improved to support the increased
data communications and to support the continuously
growing number of clients.
The graphs show the type of client (above) and the
average number of queries (right) performed
through remote CFMU terminal accesses. At the
end of the year, more than six queries were made
for each flight. This represents more than 100,000
queries per day.
A new service enabling access to CFMU archived
information (CFMU Interactive Reporting) has
been deployed, which allows clients to consult
data and statistics.

Flight plan messages grow
The general increase in air traffic during 2004 is
also reflected in the number of flight plan-related
messages processed by the Integrated Flight
Plan Processing System (IFPS) system and of
course the resulting increase in workload. The
two IFPS Units processed a total of almost 14
million flight plan-related messages during 2004,
an increase of 14.9% compared with 2003. The
number of flight plans generated from Repetitive
Flight Plans (RPLs) has slightly decreased; RPLs
are filed for approximately 45% of all flight plans.
Whereas several major companies have ceased
using the RPL system, a large number of regional
airlines and airlines on the eastern periphery
of the CFMU area have started using it. The
Route Catalogue (available for 乬what if乭 re-routings
and for validation of company route databases)
now contains in excess of 41,000 routes
(up from around 30,000 in 2003) for 18,691 city
pairs.
In 2004, an average of 80.5% of the messages
received by the IFPS were processed automatically,
a slight increase on 2003. An important initiative
to increase the automatic processing rate
was introduced in April and has had significant
results, the automatic acceptance rate increasing
from 79.4% in the first quarter of 2004 to 81.1% in
the last quarter. Improving the automatic acceptance
