RFG Overview

• ASAS-TN Malmö
• 26-28 September 2005
• Jörg Steinleitner
• CASCADE Infrastructure WP Leader, EUROCONTROL

European Organisation for the Safety of Air
Navigation
2
RFG in a Nutshell

• The RFG is a pragmatic international working
  arrangement
• EUROCAE, RTCA, Eurocontrol, FAA, Australia, Japan
• Defining the requirements for a first package of
  ADS-B out and ADS-B in applications
• Developing SPR INTEROP documents for
  publication by EUROCAE WG51/RTCA SC-186
• Means of compliance for airworthiness
  operational approval
• As input for (updates of) MASPS and MOPS
• Providing material to and liaising with ICAO
• Now implementation oriented, flexible and
  adaptive

3
RFG Approach

• Use of two key references
• CARE/ASAS Description of a first package of
  GS/AS applications
• EUROCAE ED78A/RTCA DO-264 Guidance Material for
  Approval of Air Traffic Services supported by
  Data Communication
• Organised as plenary group and three sub-groups
• Application Definition SG (further sub-divided in
  three task forces) ? Operational Service and
  Environment Definition (OSED) document
• Safety and Performance Requirements SG ? SPR
  document
• Interoperability Requirements SG ? INTEROP
  document
• Involvement of all relevant stakeholder
  categories
• Industry, ANSP, Airspace Users, Safety,
  Standardisation, Certification

(Revised) Working Arrangements
SYS
OPS
5
Application Batches

• ADS-B-NRA - Enhanced ATS in non-radar areas
• ASPA-SM - Enhanced sequencing and merging
  operations
• ADS-B-RAD - Enhanced ATS in radar areas
• ATSA-VSA - Enhanced visual separation on
  approach
• ATSA-ITP - In-trail procedure in oceanic
  airspace
• ATSA-SURF - Enhanced traffic situational
  awareness on the airport surface
• ADS-B-APT - Airport surface surveillance
• ADS-B-ADD - Aircraft derived data for ground
  tools
• ATSA-AIRB - Enhanced traffic situational
  awareness during flight operations

Note ASPA-CP effectively dropped from current
work programme

Overall Status

• First of all RFG is very well recognised now !
• Stabilised working arrangements methods
• Good participation from all relevant stakeholder
  categories
• Additional effort is always welcome interested
  parties join !
• Links well established to
• Implementation activities (Europe, US, Australia)
• Validation activities (eg. CASCADE CRISTAL)
• ICAO (SASP, OPLINK, SCRSP)
• (Initial) rule-making processes (JAA/EASA)
• EUROCAE/RTCA SPR INTEROP publication process
  soon to be initiated for first application
  (ADS-B-NRA)

7
Status ADS-B-NRA ADS-B-RAD

• ADS-B-NRA fast-track GSA application
• In support of near-term implementations
• SPR challenge harmonisation of EUR US OPA/OSA
  approaches
• INTEROP development truly fast-tracked
• ADS-B-NRA SPR and INTEROP documents due for
  submittal to RTCA/EUROCAE FRAC (approval target
  date Feb 05)
• RFG approval at RFG/7 meeting (10-13 October)
• Strong link established to related ICAO
  activities
• ADS-B-RAD will benefit at very large from NRA
  work
• SPR and INTEROP to be swiftly produced on back of
  NRA work

8
Status ASPA-SM

• Fast-track ASA application
• Effectively the only (remaining) RFG Spacing
  application
• Most demanding application, both procedural
  system related
• SPR challenge harmonisation of EUR US safety
  methodologies
• OPA work needs to address surveillance as well as
  operational performance aspects
• Freezing of current OSED and SPR material
• Final updates pending further on-going validation
  activities
• INTEROP document to be developed when final
  OSED/SPR available
• ASA common matter identification of target
  aircraft
• Issue relationship with UPS Merging Spacing
  activities

9
Status ATSAW Applications (1/2)

• ATSA-VSA
• First ATSAW application to be subject to SPR
  process
• Mature OSED subject to 1st ATSAW OHA workshop
  (RFG/6)
• Fully fletched SPR process to start after 2nd OHA
  workshop (RFG/7)
• SPR work largely benefiting from SM pioneering
• ATSA-ITP
• Moved up on RFG priority lists due to interest of
  key stakeholders
• Swift, efficient and high-quality OSED
  development process
• 1st OHA workshop to take place at RFG/7
• Old habits (or sometimes names) die hard
• RFG material considered by ICAO NAT ATMG as
  starting point for an ICAO developed procedure

10
Status ATSAW Applications (2/2)

• ATSA-SURF
• Mature draft available since February 2005
• New co-editors picked-up work again recently
• OSED update and issues subject to RFG/7 ops
  workshop
• ATSA-AIRB
• OSED describes 3 sub-applications with differing
  degrees of maturity
• Enhanced flight operations related to other
  traffic
• Enhanced visual acquisition for see-and-avoid
• Enhanced TIBA (Traffic Information Broadcasts by
  Aircraft)
• OSED subject to operational workshop at RFG/7
• Towards a more precise definition of procedures

11
Status Remaining GSA Applications

• ADS-B-APT
• Mature draft OSED available since February 05
• Coverage of A-SMGCS level 1 and ADS-B only
  environments
• SPR background work (A-SMCGS level 1) available
  to RFG
• Next steps reinforce OSED and initiate SPR work
• ADS-B-ADD
• The funny bird of the RFG application set
• OSED effectively to be a list of candidate ADDs
• SPR document to point to existing (non-RFG)
  material evidence
• INTEROP document to list the implementable ADD
  set

12
Conclusions

• RFG well recognised and steaming ahead
• Well established within overall standardisation
  context
• Providing key deliverables for initial ADS-B
  implementations
• Fast-track application work laying the
  foundation
• Forming the team and its working processes
• Next batch applications largely benefit from
  initial work
• ADS-B-NRA SPR and INTEROP due to be FRACed
• Other applications (GSA ATSAW) to follow
  swiftly
• ASPA-SM requiring further validation subject
  to considered harmonisation with UPS MS
  implementation activities
• RFG is there for ADS-B implementers join the
  team !
