EEC: PATHWAY
TO THE FUTURE
Safety
A Safety Management System implementation
strategy was developed and a roadmap created
to promote a safety culture in EUROCONTROL
projects under development at the EEC.
A safety methodology is being developed
according to four main principles:
仭 Adapting and enhancing general safety
assessment methods.
仭 Gaining a top-down model of safety for the
medium-term.
仭 Learning from safety-related events.
仭 Building safety into the concept development
phase of projects.
These approaches are being tested on a number
of projects. The overall assessment process
comes under the heading of Safety Assessment
for New Designs (SAND).
A complementary 乪top-down乫 approach is
being developed, addressing three research
areas and the whole future ATM Gate-to-Gate
Concept, to determine where the main risks
lie, and where investment in safety is most
needed.
The Saflearn approach helps to decipher the
lessons learned from current and past safetyrelated
events. This has been successful in gaining
safety-related data from three ANSPs and
using it in 乪safety learning exercises乫, whereby
future concepts can benefit from currentand
past incidents.

Since it started tactical operations in 1995 the
EUROCONTROL Central Flow Management Unit
(CFMU) has set new standards for air traffic flow
management (ATFM) in European airspace. Delays
caused by ATFM have been steadily reduced,
while traffic growth has resumed strong growth
after the September 11 attacks.
The CFMU is constantly looking for, and introducing
improvements to ensure it can accommodate the
predicted doubling of traffic using European airspace
by 2020. It has also been called upon to
adapt to changing circumstances with the aim of
providing better value to air navigation service
providers (ANSPs) and airspace users.
Traffic had already reached unprecedented levels
in 2003, with an average of 23,197 flights per day,
a rise of 2.8% compared to the previous year. 2004
saw a new record set for the average growth in traffic,
at 4.5%, while the accumulated average delay
per flight remained at the same level (1.7 minutes
per flight). The efforts by the CFMU to maintain its
principal function, matching demand with capacity,
are therefore succeeding. However, they must continue
if the present trend is to be maintained.
The basic objectives of flow management continue
to be the provision of safe, efficient and cost effective
ATFM services. The continued deployment of
the Enhanced Traffic Flow Management System
(ETFMS), introduced in 2002, supports these
objectives. The Air Traffic Flow and Capacity
Management (ATFCM) strategy emphasises that
the use of ATFM should be extended beyond slot
allocation mechanisms to the optimisation of traffic
patterns and capacity management. This strategy
is being carried out.
In addition to improving the CFMU's own processes,
the global ATM environment in which it operates
is also evolving. Given the CFMU's pan-European
role, it is all the more important that its systems can
adapt, allowing the CFMU to integrate its services
more easily within the developing, collaborative,
ATM environment.

PAN-EUROPEAN
FUNCTIONS
By definition, EUROCONTROL乫s work is carried out
at European level, with the aim of maximising the
safety and efficiency of the civil and military air
traffic management network. Efficiencies arise from
the economies of scale inherent in working on a
pan-European basis, while EUROCONTROL brings
added value by providing services which are far less
expensive than if they were provided by each individual
service provider.
EUROCONTROL also brings impartiality to the provision
of services because it is equally responsible
to all Member States and provides an identical service
to all, while respecting the priorities of its governing
bodies.
Traffic growth in 2004
The decline in traffic in 2001 and 2002 recovered
fully in 2003 and increased in 2004. The
largest number of flights processed across
Europe on a single day was 29,495 on 10
September 2004 a growth of 4.6% compared to
the busiest day in 2003. The 2003 record was
exceeded on 33 other days in 2004.
It is important to note that the growth in demand
is not uniform. Some areas have experienced
