2. ETFMS DATA REDISTRIBUTION
Purpose: to supply ANSPs and AOs with flight data from ETFMS in a message.
Same as the Flight data that can be viewed on Network Operations Terminal (CHMI) or NOP Portal.
It allows to have a common view on ATFCM flight data.
Develop local ATFCM tools such as TLM, other future ATFCM applications and flight following applications.

4. PHASE 2 - DATA RE-DISTRIBUTION
ETFMS Flight Data (EFD) message.
Sent at significant flight data updates in ETFMS.
Sent to interested sites, via a value added network.
ADEXP format.
Requirements defined in close cooperation with ANSPs.
Available since 3 Nov 2004.

5. EFD CONTENTS
Standard fields such as Callsign, ADEP, ADES, IFPLID, ....
Special fields such as event, rdystate, fltstate, afregullist ...
ETFMS point profile, and airspace profile for the three ETFMS flight models.

6. EFD TRANSMISSION EVENTS
Flight plan reception and flight plan updates from IFPS.
ATFM events such as slot issue, slot re-calculation, ...
Flight status changes such as suspension, tact-activation, ATC-activation, termination, …
Periodic transmission.

8. EFD FILTERING FOR ANSPs (1/3)
ETFMS produces EFDs that are distributed in broadcast by the ETFMS-CS to all ENs equipped for DDS.
The EN filters not-required EFDs, it only forwards relevant EFDs to the ATS system.
The EN allows the definition of user dependent message filters.
The EN allows the definition of user dependent field filters.

9. EFD MESSAGE FILTERING FOR ANSPs (2/3)
Available message filters
Elementary Sector (ES) check Discard EFDs with only unknown Elementary Sectors. EFDs are provided for flights entering AOR.
Entry Time check Discard EFDs of which the entry time of the first ES - parameter is in the future.
Exit Time check Discard EFDs of which the exit time of the last ES + parameter is in the past.
Event exclusion Discard EFDs that are generated for certain events.
Flight state exclusion Discard EFDs that have a certain flight state.

10. EFD FIELD FILTERING FOR ANSPs (3/3)
Optionally the EN may remove certain fields from the EFD message.
Available field filters:
Point Profile
Remove the Point Profile from the EFD before sending.
Airspace Profile
Remove the Airspace Profile from the EFD before sending.

11. EFD FILTERING FOR AOs (1/3)
ETFMS produces EFDs and these are distributed in to an EN that is especially and only configured for DDS to AOs.
The EN will filter out not-required EFDs or EFD fields. It will only forwards relevant EFDs to the AO’s system.
The EN will only output EFDs for flights that “belong” to the AOs that participate to this new Data Distribution Service.
Determination of the AO of a flight:
From the 2-3 first letters of the Aircraft Id
From Field-18 /OPR

12. EFD FILTERING FOR AOs (2/3)
The EN may implement additional filters.
For example: Flight plan cancellation, termination,...
Conditions
All AOs need to agree on the same filter settings.
Benefits
Reduction of required (network) bandwidth

13. EFD FILTERING FOR AOs (3/3)
Available message filters
Event exclusion Discard EFDs that are generated for certain events.
Flight state exclusion Discard EFDs that have a certain flight state.
Available field filters:
Airspace Profile
Remove the Airspace Profile from the EFD before sending.

14. EFD BENEFITS
The EFD supplies ANSPs and AOs with the same flight data as available in ETFMS-CS.
It can be used to reduce the number of inconsistencies in data between ETFMS, ATC and AO systems.
It allows to have a common view on flight data.
It is an enabler for Collaborative Decision Making (CDM).
It will bring great benefits for the further developments of ATFCM.

15. DATA DISTRIBUTION STATUS FOR ANSPs

16. ETFMS PHASE II WORKSHOP
On 25/06/2003 in Brussels.
Purpose: To obtain a better understanding on how ETFMS re-distributed data can be used for the further development of ATFCM.
70 participants from 23 different ANSPs and Airlines and Controllers associations.
Presentations by 6 ANSPs and discussion by all.

17. ETFMS PHASE II WORKSHOP
CONCLUSIONS
ETFMS Data Re-distribution will improve data quality and sharing. Common view on ATM data, extend horizon, works on quality of information.
ETFMS Data Re-distribution will require tools. Enhance existing tools (TLM), new tools, standardization, consistency with existing CFMU tools.
ETFMS Data Re-distribution gives the opportunity to further develop procedures. New tools will raise opportunity for development of procedures but information is not yet mature. CAMES project.
Regulatory aspects have to be taken into consideration to prevent misuse of information.
