ENHANCED TACTICAL FLOW MANAGEMENT SYSTEM (ETFMS) WHY ? EDITION 16/01/2013 Hans Koolen

TACT/ETFMS - MILESTONES March 1995 : Start of Operations of TACT based upon FPL data only. April 1995 : 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.

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.

Improved Accuracy and Prediction Improved Slot Allocation 4 AREAs of ATFCM IMPROVEMENT Improved Accuracy and Prediction Improved Slot Allocation Departure Monitoring Effect on Operational ATFM Procedures

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.

84% of flights are updated with an average of 83 CPRs per flight IMPROVED ACCURACY AND PREDICTION (2) 84% of flights are updated with an average of 83 CPRs per flight

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

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

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

COMMON VIEW on ATFCM data increased 12 times COMMON VIEW – NETWORK OPERATIONS TERMINAL 1998 - 290 Users 182 AOs 64 FMPs 13 (other) ANSPs 28 Airport & Handlers 3 Others 2013 - 3389 Users 1524 AOs 77 FMPs 271 ANSPs 1138 Airport & Handlers 379 Others COMMON VIEW on ATFCM data increased 12 times

DDS to Airports of Destination COMMON VIEW – Data Distribution Services DDS to ANSPs Used by 7 ANSPs (EH, EG, EK, LS, LI, ED & EDYY) For Traffic Load Monitoring and AMAN horizon extension DDS to AOs Used by 88 AOs (represent 45% of NMOC traffic) For Flight Following applications DDS to Airports of Destination Used by 15 airports For receiving an early Estimated LanDing Time (ELDT) Status on 08/01/2013

For use in their own ATFM Applications Status on November 2012 COMMON VIEW – NM B2B web services Used by: 59 AOs 43 CFSPs 24 handling Agents 25 ANSPs 6 Airports 6 other For use in their own ATFM Applications Status on November 2012

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.

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

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.
