EFD FILTERING

• ETFMS produces EFDs 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

• 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

• 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 BENEFITS

• The EFD supplies ANSPs with the same flight data
  as available in ETFMS-CS.
• It can be used to reduce the number of
  inconsistencies in data between ETFMS and ATC.
• 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 .

Data Distribution status
13
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.

14
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.
