2. TACT/ETFMS - MILESTONES
March 1995 : Start of Operations of TACT based upon FPL data only.
April : Reception of first airborne update (FSA) message from France.
March 2001 : ETFMS PHASE 1a operational, based upon FSA data only.
7 Feb 2002 : ETFMS PHASE 1a operational, based upon FSA data and surveillance data from UK, France and MUAC.
6 May 2003 : Flight Activation Monitoring (FAM) Operational for Ireland, Oslo FIR and Belgium.
Today : Reception of FSAs from 32 countries (57 ACCs), CPRs from 28 countries (49 ACCs) and oceanic clearances from 3 oceanic centres.

3. ETFMS - OBJECTIVES
To increase the accuracy of ATFCM thus reducing any differences in data between ATFCM, ATC and airports.
To improve short-term traffic demand forecasts.
To reduce over-delivery.
To enable more accurate slot allocations thus improved utilisation of the available capacity.
To improve reaction to short-terms events.

4. Improved Accuracy and Prediction Improved Slot Allocation
4 AREAs of ATFCM IMPROVEMENT

Effect on Operational ATFM Procedures

5. Many Airborne Updates FSA messages (05 November 2012):
IMPROVED ACCURACY AND PREDICTION (1)
Many Airborne Updates
FSA messages (05 November 2012):
99,900 FSA messages received .
for 25,800 flights, 96% of flights updated.
average of 3.9 FSAs per flight.
CPRs (05 November 2012):
2.15 million received
for 25,800 flights, 88% of flights updated.
average of 83 CPRs per flight.
 More accurate flight profiles in ETFMS.

6. 84% of flights are updated with an average of 83 CPRs per flight

11. Reduction in over-deliveries from 7% to 4.9%.
IMPROVED SLOT ALLOCATIONS
ATFM simulations on 4 different days of Jan/Feb 2005, comparing ATFM situation with and without airborne data.
Reduction in over-deliveries from 7% to 4.9%.
Reduction in number of delayed flights by 7%.
Reduction in ATFM delay by approximately 17%.
 2.5 million min of ATFM delay reduction.
Delay reduction due to capacity increase, not measured

12. EFFECT ON OPERATIONAL PROCEDURES
Better overall view on Traffic Situation for NMOC (CFMU) for Tactical Flow Management
Look at network effect during Tactical Operations
Can only be done with reliable/accurate flight data
Optimise ATFM Daily Plan (delete / modify regulations) by NMOC (CFMU)
Increased confidence in counts by ATC
Management of Critical Events
Strikes, runway closure, ...
Search for special flights

13. DDS to ANSPs, AOs and Airports
COMMON VIEW – summary
Common View: Operational Flight data is shared with all ATM stakeholders in the network
CHMI and NOP portal
More than 2300 users
For daily operational traffic view
DDS to ANSPs, AOs and Airports
Used by 7 ANSPs, 88 AOs, 15 airports
For TLM, AMAN, Flight Following and ELDT reception
B2B web services
Used by more than 150 stakeholders
For obtaining operational ATFM Flight data

17. Flight Activation Monitoring (FAM) increases accuracy.
DEPARTURE MONITORING
In August 2007:
67% flights are monitored.
18.5% are updated.
533 flights suspended.
286 updated by AO after suspension
108 never updated  Ghosts.
(139 airborne when suspended)
Flight Activation Monitoring (FAM) increases accuracy.

18. ETFMS - BENEFIT PROCESS
IMPROVED ACCURACY OF ATFCM DATA
MORE Network operations TERMINALS
IMPROVED ATFCM TRAFFIC DELIVERY
ETFMS DATA REDISTRIB.
IMPROVED ATC CONFIDENCE
COMMON VIEW on ATFCM SITUATION
OPTIMISED USE OF INCREASED CAPACITY
DEVELOPMENT OF NEW ATFCM METHODS
Optimised ATM & Reduced
Management Delays

19. CONCLUSION
ETFMS increases accuracy of ATFCM.
ETFMS reduces ATFM delay.
ETFMS enables a common view on the Air Traffic Situation in ECAC.
ETFMS is an enabler for future developments in ATFCM.
