Attachment A
THE AIR TRAFFIC FLOW MANAGEMENT
SYSTEM OF THE EUR REGION (ASTER)
DEVELOPMENT
1. The development of the ASTER service should be
adapted to the level shown to be necessary to ensure its aim.
Particular care should be taken to ensure maximum cost
effectiveness.
PRINCIPLES
2. The ASTER service should be based on the
following principles:
PRINCIPLE 1. The service provided by the ASTER should
be made available to all States in the EUR region. Provision
of the service must also adequately cater for the
requirements of flight operations to and from States
adjacent to the region.
PRINCIPLE 2. States should choose either of the two
central management units (CMUs) best suited to meet their
operational requirements. This should not preclude a State
from cooperating with both CMUs when required.
PRINCIPLE 3. The ASTER shall use continuously updated
data reflecting expected and current traffic demand and
capacity within the EUR region.
PRINCIPLE 4. The ASTER should optimize available
capacity and assist with preventing overloads of the ATC
system, in order to minimize adverse effects upon aircraft
operators.
PRINCIPLE 5. Close coordination should be maintained at
all times between the CMUs, flow management positions
(FMPs), the ATC units served and aircraft operators.
PROVISION OF SERVICE
PRINCIPLE 6. Close coordination should be maintained
with military authorities, as appropriate.
PRINCIPLE 7. The ASTER should be sufficiently staffed
with appropriately trained and qualified personnel.
PRINCIPLE 8. The ASTER service should be available on
a 24-hour basis.
PRINCIPLE 9. Efficient and reliable communications
should be available between CMUs, FMPs, the ATC units
served and aircraft operators.
CONCLUSION: The ASTER should operate in partnership
with the ATS providers and aircraft operators. It cannot be
a directive organization as the other partners have
regulatory (safety and economic) regimes to live within,
and different stakeholder/shareholder expectations.
RESPONSIBILITIES
AND RELATIONSHIPS
3. The two CMUs will act to support ATS providers
and aircraft operators by being responsible for the planning,
coordination and execution of all ATFM measures within
their respective areas of responsibility, in accordance with
the procedures defined in the appropriate handbooks. The
FMPs will be responsible for the local management of these
measures.
Note.— Detailed information pertaining to the
responsibilities and relationships associated with the
provision of ATFM within the CFMU area of responsibility
is contained in the EUROCONTROL Basic CFMU
Handbook.
