●
To enable more accurate slot allocations thus improved
utilisation of the available capacity.
●

DATA INPUT
FLIGHT DATA UPDATE
●
Airport CDM systems send early estimates of Take-OffTimes, SIDs and TaxiTimes.
● They are sent when a change is entered in an ATC or
Airport CDM system.
●
The flight data updates are for indicating changes in the
flight plan, once the flight is airborne (AFP, FSA).
●
Changes concern the route (short cuts, CDR3, ….), the
Cruising level, estimates and in the future possibly
diversions.

DATA INPUT
DEPARTURE PLANNING INFORMATION MESSAGE (DPI)
●
DPI: Receive flight data updates while flight is still
on the ground.

DATA INPUT
FIRST SYSTEM ACTIVATION MESSAGE (FSA)
●
The purpose of the FSA is to provide estimates and route updates to
the NMOC (CFMU) for ATFCM purposes.
●
●
●
FSA shall be sent via AFTN/CIDIN to the ETFMS-CS directly.
FSA messages are sent by ANSPs.
FSA shall be sent in the following circumstances :

FUNCTIONS
●
●
●
●
●
Monitors flights which should have departed.
Identifies flights which should have departed and for
which no message is received to confirm their departure.
“Updates/Shifts” these flights until a message is
received.
If no update is received after 30 min, the flight is
suspended.
Informs the AOs of a suspension enabling them to react.

OBJECTIVES

from
ETFMS data to improve Traffic Load
● Allow a more efficient use of the available capacity.
● Provide an incentive for Aircraft Operators to update
●

Reduce the impact of ghost flight plans and of late
departures.

32
FLIGHT ACTIVATION MONITORING (FAM)
APPLICATION
● Only for flights in areas from which ETFMS receives
CPRs for all flights.
●
●
Operational for first states since 06/05/2003.
Target: All states from which CPRs are received.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
33
FLIGHT ACTIVATION MONITORING (FAM)
EXPECTED RESULT
● FAM will release slots which are unduly
occupied by flights not departed, thus
making these slots available for other
aircraft which are ready to depart.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
34
APPLICATION OF FAM (1)
●
FAM is applied on all flights, whether regulated or not,
departing from and/or landing at areas where CPRs are
received by the NMOC (CFMU) and FAM is activated.
● Flights departing from and landing in non FAM enabled
areas are NOT affected by FAM, irrespective if they fly
through CPR covered or non CPR-covered FAM enabled
areas en-route.
● CPR coverage is an essential requisite for FAM to be
applied. When CPR coverage in a particular area is not at
the level considered as “safe”, then FAM is deactivated for
his area.
●
Where FAM is applicable, the timing starts at the entry of
the first CPR-covered FAM enabled area (AUA).

39
OUTPUT
IMPACT ON COUNTS AND FLIGHT LISTS
●
Having flight profile forecasts increases the
accuracy of the traffic prediction.
●
The counts on any sector/aerodrome take
into consideration the profile recalculation.
●
Flight lists and summaries are updated
accordingly.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
40
OUTPUT
IMPACT ON THE SLOT ALLOCATIONS
●
Same scenario for flights changing route :
vacant slots are re-used, overload slots are
compensated if possible.
●
As statistics show that on average flights
are late, it improves the delay situation.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
41
OUTPUT
IMPACT ON TRAFFIC MONITORING
●
Both departed and not-yet-departed traffic
are updated.
●
Both regulated and non-regulated traffic are
updated.

Traffic forecast is improved.

Potential overloads will be detected earlier.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
42
OUTPUT
IMPACT ON ATFCM IN GENERAL
●
Improving the use of available capacity reduces delay
(dynamic slot lists).
●
Increased accuracy of the information provided to users.
Improve Traffic smoothing (less “bunching”).
●
Improved monitoring of slot compliance.
●
Consequence: increased confidence in ATFCM is expected
to lead to increases in capacity provided to ATFCM.
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
43
OUTPUT
IMPACT ON NMOC (CFMU) OPERATIONS
●
Greater accuracy of the traffic load, permitting less
“unnecessary” actions being taken (no longer creation
of regulations “just in case”).
●
Improved ability to manage “unusual” situations in real
time (given the more accurate data on actual traffic
demand).
© EUROCONTROL 2013 – Network Manager Operations Centre (NMOC/CFMU)
44
OUTPUT
IMPACT ON FLOW MANAGEMENT POSITIONS (FMPs)
●
Because of the improved accuracy of the data in ETFMS,
FMPs will have earlier warning of demand which, for
whatever reason, is exceeding the declared capacity.
●
This earlier warning will permit the FMP to consider and
perhaps implement some further remedial actions to reduce
the impact :

Level capping.

Sector organisation.

Warnings to controllers.

Rerouteings.

45
OUTPUT
IMPACT ON AIRCRAFT OPERATORS (AOs)
●
Less delay.
●
Greater accuracy in the flight plan data on the CIA, in
particular for the arrival time.
●
Improved ability to maintain in good time, accurate
EOBTs for the return and subsequent legs for a
flight/aircraft.

EU Implementing Rule 255/2010
●
COMMISSION REGULATION (EU) No 255/2010 of 25
March 2010 lays down common rules on air traffic
flow management
●
It defines in Article 6/5: ATS Units shall provide NMOC
with following data and subsequent updates:
 (f) updated flight positions (i.e. CPR & FSA)
 (g) deviations from flight plans (i.e. FSA & AFP)
 (i) actual take-off times (FSA)

CONCLUSION
●
ETFMS is an important step in the improvement of the
ATFCM process.
●
A critical step because numerous data will be used for the
first time and systems will have to be adapted for their
interpretation.
●
Areas for special attention:
●
●

Quality of received data.

Quality of prediction and extrapolation algorithms.
It will require fine-tuning for all areas and processes.
ETFMS will allow ATC to share information on the flight
data.
