  1. EUROCAE Dedicated to Aviation Standardisation ASAS Standards: “From concept to equipment” DavidBowen (Technical Secretary) April 24th 2007

  2. Why Standardize? Regulator User Manufacturer Standards ensure safety and interoperability Standards facilitate procurement Standards provide means of compliance A single standard which meets different needs Safety and Interoperability Cost (development and procurement)

  3. The Process crosses the boundary of responsibility of various organisations which must cooperate throughout the development lifecycle From Concept to Equipment High Level ATM Concept Principles of ASAS Operational Application Descriptions Operational Requirements Safety and Performance Requirements System Requirements (Interop) System Description (Architecture) Equipment Specifications

  4. Evidence in the Operational Approval of the ASAS Application Certification of Avionics Supporting Legislation High Level ATM Concept Principles of ASAS Operational Application Descriptions Operational Requirements Safety and Performance Requirements System Requirements (Interop) System Description (Architecture) Equipment Specifications

  5. ICAO FAA EASA EUROCONTROL SAE EUROCAE RTCA ESO’s ARINC European Commission WORLDWIDE AIRWORTHINESS SYSTEM SARPs (E)TSO’s TGL’s ESSARs MOPS MASPS Guidelines European Standards (IR’s and CS’s) European Regulatory Framework

  6. ERs IRs Community Specifications The Interoperability Legislation Essential Requirements Implementing Rules

  7. Document Relationships Additional CS specific Material The Essential Requirements Community Specification Compliance Referenced Material Implementing Rules EUROCAE Document ED-XXX EUROCAE Document ED-YYY Eurocontrol Document ICAO Documents and Manuals

  8. Concept and Context High Level ATM Concept Principles of ASAS Operational Application Descriptions Operational Requirements Safety and Performance Requirements System Requirements (Interop) System Description (Architecture) Equipment Specifications

  9. Concept and Context High Level ATM Concept Principles of ASAS The highest level of the end to end process is the setting of the ASAS concept in the context of the European and Global ATM Concept – Clearly in Europe this must relate to the SESAR Concept being Established today. ICAO Provisions for the use of ASAS within global ATM

  10. Requirements The Core of the Process is translating general principles to implementable applications which results in requirements on the system which enables the application. Operational Application Descriptions Operational Requirements Safety and Performance Requirements System Requirements (Interop) This relates to the ED87a methodology developed for datalink communications applications but now being applied to early ADS-B applications, including ASAS, within the RFG

  11. Requirements Methodology • ED-78A “GUIDELINES FOR APPROVAL OF THE PROVISION AND USE OF AIR TRAFFIC SERVICES SUPPORTED BY DATA COMMUNICATIONS” • This document is identical to RTCA DO-264 and the development of these guidelines was jointly accomplished by (EUROCAE) WG-53 and RTCA SC-189 • The Methodology Results in the Following: • Operational Services and Environment Definition (OSED) • Operational, Safety, and Performance Requirements (SPR) Standard (developed using an operational safety assessment (OSA) and an operational performance assessment (OPA)) • Interoperability Requirements (INTEROP) Standard

  12. ASAS • RFG has applied this Methodology to initial (Package 1) ADS-B applications including Airborne Applications. • The first Application (ADS-B NRA) document ED-126 (including OSED, SPR and Interop) has been published (though for a GSA) • Initial Airborne applications are progressing and will be published this year. • Each Application requires significant effort and resources. • Early part of the process is operationally intensive with technical elements increasing towards the end of the process. • An iterative approach is vital.

  13. Equipment Standards The final part of the process (in the technical dimension) is the specification of the system and equipments which can meet the requirements and allow implementation of the application. MASPS and MOPS (Performance Specifications) then need to be developed Equipment Specs (Interface etc) giving more details on boxes, interfaces etc may also be developed as Industry Standards System Description (Architecture) Equipment Specifications

  14. Equipment Standards Development GSA ADS-B Applications ASAS Applications (SPR and Interop) Consolidation of Requirements System Performance and Architecture MASPS Equipment Specifications Transceiver MOPS Other Avionics MOPS Groundstation Specification

  15. Initial set of applications under RFG Development (Joint EUROCAE/RTCA and Eurocontrol/FAA Initiative) bringing together operational and technical expertise. Subsequent application development will link into SESAR Equipment Standards Development GSA ADS-B Applications ASAS Applications (SPR and Interop)

  16. RTCA SC186 and EUROCAE WG-51 continued responsibility for the equipment standards Equipment Standards Development System Performance and Architecture MASPS Equipment Specifications Transceiver MOPS Other Avionics MOPS Groundstation Specification

  17. Target • Operational Approval and Certified Equipment (EASA) • Compliance to the Essential Requirements and Implementing Rules (Community Specifications) • Equipment Specifications for Industry • Detailed Application Descriptions ASAS Application Definitions System Performance and Architecture Equipment Performance Specifications EASA Certification and Approval SES Interoperability Legislation Compliance

  18. Review • Overall Standards should cover: • Operational Descriptions and Context • Technical Requirements and Specifications • Participation in the Standards development required from: • Regulators, ANSPs and Industry • Including expertise from: • Aircrew, Controllers, Engineers and Safety Experts • Initial work in RFG must be continued in the context of the SESAR Concept to realise benefits. • For ASAS implementation, continued commitment from all stakeholders is required in the Standards Development Process – From End to End.
