where traffic density is low, creates an
experience platform before introduction
in a denser traffic environment.
Fast-time simulations performed by
both EUROCONTROL and LFV in the
area concerned have indicated that the
distance flown using optimum route
selection is 1-2% shorter than within
the fixed route network. For every 1,500
flights, the implementation of FRAS is
expected to bring a daily reduction in fuel
burn of more than 20 tonnes, reducing
CO2 emissions by more than 60 tonnes.
Another piece of good news is that for
airlines the FRAS concept does not
require any additional equipment.
Furthermore, the implementation of FRAS
increases consistency between the flight
plan and the trajectory flown. This is an
essential part of the improvement of the
gate-to-gate process and the development
of future ATM tools to facilitate it.
A representative of the operational division
of the Swedish Air Force has been
involved in the FRAS project since it
started at the end of 2007. This has
ensured that the operational concept
which has been developed provides
improved flight efficiency for both OAT
and GAT.
As part of the Flexible Use of Airspace
concept, TRAs (Temporary Reserved
Areas) are also being established in
Sweden. These areas will be active
during specific military exercises, giving
limited access to non-participating
traffic. In these cases, the traffic will be
routed tactically outside active TRAs.
The implementation of free route
airspace is enabled by the adequate
system support provided at the two
Swedish ACCs (Stockholm and Malmö),
in the form of MTCD (Medium-Term
Conflict Detection) and APW (Area
Proximity Warning). These augment
conflict detection and track monitoring
capabilities. Close cooperation with
military counterparts at both planning
and operational levels is already well
established.
The larger the area encompassed by a
portion of free route airspace, the larger
the benefits in terms of the environment
and flight efficiency for the airspace
users. Ongoing discussions with neighbouring
States indicate that this concept
will expand within the region in the very
near future. n
FRAS, Free Route Airspace Sweden, is an initiative of the Swedish LFV
Group. It falls within a project known as Green Flight, part of a wider
programme called RAM, the Regional ATM Migration Programme.
Peder Albèr, Project Manager FRAS, LFV Group, explains.
Sweden implements free route
airspace above FL 285 in a phased
process from 2009 to 2010

Interview
Following the recommendations of the wide-ranging feasibility study on
the creation of the Functional Airspace Block Europe Central (FABEC),
and the signature, last November, by Belgium, France,
Germany, Luxembourg, the Netherlands and Switzerland
of a joint Declaration of Intent for the creation of FABEC,
the implementation phase was officially launched in
November 2008 among the civil and military air
navigation service providers and the State authorities
of the six States. The FABEC Project Manager,
Peter Naets, reveals the issues at stake.
“FABEC is all about believing that
together, we can make it”
Since the very beginning, the
FABEC project has had the
ambition to federate all the
actors of the air navigation
sector in the area – whether
they represent civil or military
State authorities or civil and
military air navigation service
providers. What kind of structure
did the parties put in
place to drive the implementation
phase and facilitate the
integration process?
The FABEC project has been considered
as a single project from the outset.
It therefore rests on a three-pillar governance
structure, where all partners
are closely interrelated –
the States
Organisation, the Project Organisation
and the Air Navigation Service
Providers (ANSPs) Organisation. We
opted for this structure to ensure a
clear and consistent allocation of
responsibilities and accountabilities for
all the improvements to be put in place
by the different partners. Because all
activities should converge and are as
complementary as are the many parts
of a vast jigsaw, there is a single integrated
work plan for ANSPs and the
States alike, the objective being to
eventually build a coherent whole. We
wanted to put in place an organisation
