SLOT ALLOCATIONS SLOT ALLOCATIONS

● No change in allocation mechanism.

● Slot lists are updated based upon the actual position and the recalculated profile (forced).

● Released slots may be re-used for other flights.



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.

FLIGHT ACTIVATION MONITORING (FAM)FLIGHT ACTIVATION MONITORING (FAM)


OBJECTIVES

● Benefit from ETFMS data to improve Traffic Load counts.

● Allow a more efficient use of the available capacity.

● Provide an incentive for Aircraft Operators to update their EOBTs.

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



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.



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.



● 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).

SUMMARY SUMMARY

● Improved (short-term) load prediction.

● Improved traffic smoothing.

● Reduced delays.

OUTPUTOUTPUT


IMPACT ON COUNTS AND FLIGHT LISTS 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.

OUTPUTOUTPUT


IMPACT ON THE SLOT ALLOCATIONS 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.

OUTPUTOUTPUT


IMPACT ON TRAFFIC MONITORING 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.

OUTPUTOUTPUT


IMPACT ON ATFCM IN GENERAL 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.

OUTPUTOUTPUT


IMPACT ON NMOC (CFMU) OPERATIONSIMPACT 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).

OUTPUTOUTPUT


OUTPUTOUTPUT

IMPACT ON FLOW MANAGEMENT POSITIONS IMPACT ON FLOW MANAGEMENT POSITIONS (FMPs)(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.


OUTPUTOUTPUT

IMPACT ON AIRCRAFT OPERATORS IMPACT ON AIRCRAFT OPERATORS (AOs)(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.


OUTPUTOUTPUT

IMPACT ON REMOTE CLIENT APPLICATION IMPACT ON REMOTE CLIENT APPLICATION (CHMI)(CHMI)

● Figures in traffic counts and flight plan data are more accurate.

METEO DATAMETEO DATA

IMPLEMENTATION OF METEO DATA IMPLEMENTATION OF METEO DATA

● Use wind speed and wind direction in flight profile calculation.

● Forecasts for 6 periods of 6 hours, in total for 36 hours. It is updated every 6 hours.

● Forecasts for flight levels: 050, 100, 140, 180, 240, 300, 340, 390, 450, 530.

● At update of meteo data only not-activated flights are re-calculated.


SECTOR OCCUPANCY COUNTSSECTOR OCCUPANCY COUNTS

● Count the number of flights actually present in the sector at a given moment in time.

● Enabled by the improved accuracy of the ETFMS flight profile.

● Occupancy counts for counts in the near future (e.g. < 60 min).

● Average Occupancy counts for counts in the more distant future (e.g. > 60 min).


NMOC (CFMU) DATA RE-DISTRIBUTION

CONCLUSIONCONCLUSION

● 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.
