  1. CFMU User Forum ‘09 Why Flight Plan and ATFCM adherence? Christian Faber Head of Investigation

  2. The problem Traffic exceeds capacitiesby more than 10% = ATFCM "over delivery" • Not flying at the requested flight level (RFL) • Arriving in the sector earlier or later than planned • Departing at times different from EOBT/CTOT • Deviating from their original planned route Network effect impacting SAFETY! CFMU User Forum 2009

  3. FL380 FL340 re-filed FPL Example 1 regulated airspace “Request FL 380!” ADEP ADES distance CFMU User Forum 2009

  4. Example 2:over delivery in Austria 16 flights flying higher than filed 53 CFMU User Forum 2009

  5. What’s the effect… • Potentially excessive workload, • Wasted capacity in some sectors, • An overall lack of confidence in the accuracy of forecast traffic counts, • Protective capacity reduction, • Increased workload, stress or working conditions such that the ability of ATC controller may be significantly impaired and thus a safety issue. CFMU User Forum 2009

  6. FPL route - real route CFMU User Forum 2009

  7. Actual routes FPL routes The network impact CFMU User Forum 2009

  8. Flight Plan and ATFCM adherence awareness campaign • Three main elements of adherence • Adherence to requested FL (one of the main reason for over-deliveries) • Adherence to Flow Measures, mainly CTOT (thus arriving too early/late in the sectors) • Adherence to filed route (incomplete or incorrect ATFCM picture) • Procedures and rules exist already CFMU User Forum 2009

  9. ICAO Doc 7030/4 (EUR) “ATC is responsible for departure slot monitoring at departure aerodromes…” “…Aircraft operators shall inform themselves ofand adhere to… current ATFM measures…” “Any changes to the EOBT of more than 15 minutes for any IFR flight within the IFPZshall be communicated to the IFPS” CFMU User Forum 2009

  10. Commission regulation (EC) No 1033/2006 (1st January 2009) “The operator shall ensure that the conditions of acceptance of a flight plan and any necessary changes thereto as notified by IFPS to the originator are incorporated into the planned flight operation and communicated to the pilot.” “The operator shall ensure prior to operation of the flight that the content of the initial flight plan correctly reflects the operational intentions.” CFMU User Forum 2009

  11. Possible reasons for non-adherence(received via ‘Support Request’ on Skybrary) CFMU User Forum 2009

  12. Recommendations(received via ‘Support Request’ on Skybrary) CFMU User Forum 2009

  13. What has been done? • Publications: Website*, brochures, flyers, posters, presentations, WBT (e-learning) • Promotion with international organisations and working groups: IATA, IACA, IFATCA, IFALPA/ECA, IFALDA, ODSG, DOP • Contacted: ANSPs, ACCs, AOs, AOs military, FPL Service Providers to AOs, Airports, Pilots (via IATA / IFALPA), Industry. CFMU User Forum 2009 *http://www.eurocontrol.int/dmean

  14. What has been done? • CTOT adherenceFollowing countries are/were involved or have been contacted regarding CTOT adherence:EB, LK, HE, LF, LG, LH, LT, EG • OPS evaluationMaastricht and Rhein UAC operational evaluation of requested FL • TrainingSkyGuide include subject in ATCO refresher training (MUAC plans to do the same) • SystemSkyGuide system trial of identification of flights at differing RFL prior to ACC entry. CFMU User Forum 2009

  15. From awareness to improvements • Continue awareness activities and assessments at local, regional and network levels • Continue to address adherence issues at individual airports and ACCs with ANSPs, AOs and authorities concerned • Best Practices (local initiatives, ATCO & pilot training, etc) • Trials, comparison exercises (routes filed versus flown) and simulations to show impact • Adherence Day (see next slide) CFMU User Forum 2009

  16. Adherence Day One day operational evaluation through ‘full’ application of adherence procedures Objectives: • Measure the effect of adherence to FPL and ATFCM measures • Determine benefits arising from accurate EOBT/CTOT & RFL with regard to sector counts (potential release of capacity) • Improve the quality of FPL with regard to routes (incl. DCT) and FLs CFMU User Forum 2009

  17. Benefits of adherence • reliable and accurate data for all involved • improved predictability of traffic • improved network demand-capacity balancing • increased capacity • increased safety • flight efficiency CFMU User Forum 2009
