RTCA SC-206 first meetingWashington DC, July 2005

• EUROCAE
• Methodology Presentation
• for Air Traffic Services supported by Data/Link

2
Presentation of ED-78 MethodologyWhy does
EUROCAE recommend this methodology

• EUROCAE/WG53 and RTCA SC-189 published
  Guidelines for Approval of the Provision and Use
  of Air Traffic Services Supported by Data
  Communications (ED-78 / DO-264)
• It provides an internationally recognised
  methodology to address operational implementation
  of Data Link services
• This methodology has been successfully used to
  develop ED-120 (air traffic data-link service in
  continental airspace)
• EUROCAE requests that the development of the new
  AIS data-link documents is carried out based on
  this methodology

Presentation of ED-78 Methodology

• Covered topics
• End to End issues
• Regulatory objectives
• Operational objectives
• Actors
• Airlines
• ATS Providers
• Communication Service Providers
• Airframe / Equipment manufacturers
• Airworthiness authorities
• Operational authorities

11
Presentation of ED-78 Methodology

• ED-78 / DO-264 provides both methodology and
  guidance and templates for the following
• OSED (Operational Service and Environment
  Definition)
• SPR (Safety Performance Requirements)
• INTEROP (Interoperability Document)
• These elements are supported by
• OSA (Operational Safety Assessment)
• OPA (Operational Performance Assessment)
• IA (Interoperability Assessment)
• OSEIC (Operational Services and Environment
  Information Capture)

12
Presentation of ED-78 Methodology

• OSEIC Process
• Captures the operational objectives of the
  airspace users and ATS provider
• All stakeholders participate
• Information captured during OSEIC (OSED) is
  assessed and extended by OSA, OPA, IA processes
• OSA, OPA, IA processes
• Identify requirements
• co-ordinate requirements (ensure correct
  integration into OSED, SPR, INTEROP)
• Allocate requirements to stakeholders
• Validate requirements (necessary and sufficient
  for operational implementation)

13
Presentation of ED-78 Methodology

• OSED
• OSED is used as the basis for assessing and
  establishing operational, safety, performance,
  and interoperability requirements
• It includes
• a service description
• an environment description
• defined from
• selected services
• intended operational environment
• operational performance expectations
• selected functions
• selected technologies
• Produced by OSEIC process for initial OSED

14
Presentation of ED-78 Methodology

• SPR
• used to co-ordinate operational, safety and
  performance objectives and allocate requirements
  to stakeholders
• based on an operational safety assessment (OSA)
  and an operational performance assessment (OPA)
  of the functions, performance expectations and
  characteristics of the operational environment
  needed to support services identified in OSED

15
Presentation of ED-78 Methodology

• INTEROP
• Used to provide sufficient information to allow
  development of systems that are compatible for
  operational implementation
• It is developed based on an interoperability
  assessment of selected functions and technologies
  identified in OSED

16
EUROCAE Suggested work programme (TBC)

• OSED should be developed by WG-44
• SPR and IR should subsequently be developed by
  WG-53
• Then the final MASPS should be developed by WG-44

17
EUROCAE About a joint Committee

• EUROCAE is willing to work on the AIS D/L topic
• EUROCAE has to develop the ToR based on SC-206
  ToR (but maybe slightly different)
• The activity shall take into consideration the
  work done by Eurocontrol on related topics
• Consideration about the flow of data (wrt other
  applications)
• EUROCAE will meet RTCA end of August to make a
  decision about a joint Committee
• EUROCAE Technical Committee will address this
  subject mid-September (Technical Work Programme
  to be endorsed)
• Final decision is expected end of September
  (endorsement by EUROCAE Council)
