changes implemented during the
past year. In addition, a comprehensive
Safety Training Plan was prepared with the
aim of conducting safety training across all
functions of the Centre during 2005.
Implementing ESARRs
> At Maastricht, there is a clear commitment
to implementing and meeting all applicable
Safety Regulatory Requirements in a
pro-active way and at the earliest possible
opportunity. This will ensure the highest
possible safety standards in all activities.
> During 2004, the development of applicable
Executive Rules based on ESARRs continued,
with the MUAC being consulted on
the content and applicability of these
Executive Rules. In parallel to this, the
Centre continued with the implementation
of the SMS.
Innovating further
> Various safety surveys highlighted the
need for further study into airspace complexity
in the MUAC sectors. Complexity
has been highlighted in a number of incidents
as a key factor that can affect the
safe separation of aircraft. An airspace
complexity measurement project was
therefore organised in 2004, in cooperation
with the EUROCONTROL Experimental
Centre.
> The complexity factors that have an effect
on overall safety were assessed to determine
how they can be used to support the
safe implementation of future changes in
airspace, procedures or equipment. The
study is also expected to support other
EUROCONTROL initiatives, in particular the
Performance Review Commission (PRC)
benchmarks and the activities of the High-

2004 Safety Highlights (cont乫d)
Operations in 2004
(entire year)
Average daily capacity 3,798
Average daily traffic 3,544
Average delay per flight (minutes) 0,61
ANS cost per flight . 90,00
Costs per minute delay . 62,00
Capacity/demand ratio 1,074
Delay costs per flight . 37,20
Managing capacity
Capacity management is a core activity designed
to provide a high-quality and cost-effective service
to customers, while keeping ATFM delays at
agreed levels. It sets the global framework for the
planning of staff, airspace, systems and procedural
changes.
During 2004, several important capacity enhancement
programmes were implemented. Changes to
sector configuration management were introduced,
and innovative tactical capacity and flow
management processes also contributed to the
overall capacity gain. In parallel, human resources
continued to be optimised.
In April and May two new sectors were made available
in the Hanover and Brussels sector groups
respectively, the primary objective being to
increase air traffic safety by ensuring a better traffic
balance and curbing congestion in the busiest
sectors. The Centre now contains 16 operational
sectors, which can be managed more flexibly
according to traffic demand. A new Division Flight
Level was also implemented in the Deco sectors,
improving the balance of traffic between low and
high sectors.
Taking technical infrastructure to
new levels
Record levels of system availability
During 2004, the Maastricht data processing system
reached unprecedented levels of availability.
In June, for the first time, the 12-month reliability
figure reached 99.999051%, translating as a total
system outage of less than one minute over the
year. This is the result of tighter quality processes
that support system development and enhanced
testing measures.
Developing the new Flight Data Processing
System (FDPS)
The hardware identified at the end of July 2004
was procured and deployed at the supplier乫s
premises and at the MUAC. It will be used for the
development and testing phases and, in the second
half of 2006 will be installed in the operational
and support environments.
FDPS software requirement specifications were
refined and an amendment to the contract with
the supplier was signed at the end of December
to accommodate changes deemed necessary
to increase the usability of the system, reduce
controller workload and accommodate emerging
advanced Medium-Term Conflict Detection
(MTCD) features. This global approach will
ensure that new operational concepts are taken
into account and that the interfaces with the
existing systems are optimised before the new
system is commissioned in 2007.
