EUROCONTROL’s Air Traffi c Flow and Capacity Management system has
become an increasingly important element in the drive to reduce delays
and improve the effi ciency of the ATM system. Julian Moxon explains

THE INTRODUCTION OF centralised fl ight
planning through the Central Flow Management
Unit (CFMU) has made signifi cant
progress in linking available capacity with
demand. Since its launch in 1989, the CFMU
has gradually taken over all of the components
necessary for ensuring an effi cient and
safe fl ow management system in Europe.
It now provides a common Air Traffi c Flow
and Capacity Management (ATFCM) service
throughout the 44 nations represented
in the European Civil Aviation Conference
(ECAC) area. Along the way it has diversifi ed
its range of services considerably, and has
become a major contributor to the development
of the strategy for the next generation
of ATFCM as enshrined in the Single
European Sky (SES) programme.
“The 7 to 8 per cent reduction in traffi c
seen in 2009 as a result of the global fi nancial
crisis has not reduced the urgency for the
need to improve the effi ciency of fl ights
across the European system,” says Joe Sultana,
deputy director of the CFMU. “While delays
were close to target, localised problems, such
as a shortage of air traffi c controllers in some
areas, and system upgrades in others have
kept up the pressure on the system.”
Today, the CFMU, like the rest of the European
air traffi c management (ATM) system,
faces change as the SES begins to take shape.
The principal drivers are the need to meet
improved performance targets for the network
as a whole, the continued development
of Functional Airspace Blocks (FABs) and contributing
to a network management strategy
that brings all stakeholders together.
Bringing added value via
network management
The role the CFMU will play in the future
ATFCM environment is being debated. “It has
to demonstrate the value that it brings to
the system,” says Sultana. The SES II Roadmap,
published in June 2009, introduced the idea
of a “network management function” to assist
air navigation service providers to improve
overall effi ciency in the design and management
of routes. “There are diff erent visions
of how this will be achieved,” says Sultana.
Furthermore, while he believes the CFMU will
be a “key part” of the network management
functions relating to service provision, the
governance structure under which the entire
system will be overseen is still under review.
That said, moving towards a network-centred
approach to operations has been a core
function of the CFMU since it was formed. Its
strategy, presented in its 2010-14 business
plan, lies along three major axes:
u the evolution of current ATFCM activities
towards a wider network operations
approach;
u facilitating ease of access to the network
by aircraft operators;
u managing information so that all
stakeholders can obtain the latest data
necessary for their operations.
Much of the work on network performance
