(SICASP/6 Feb.97) ANB task CNS9701 Other panels are looking at airborne surveillance and airborne separation from different perspectives: –OPLINKP worked on ADS-B applications (ADS-B NRA) and produced an ADS-B concept of use. –SASP worked on separation minima based on ADS-B. –ATMCP worked on a global ATM operational concept for the years 2020 and onwards. Historical ANConf/11 ASAS implementation guidelines Required Surveillance Performance ASAS concept of use Perspectives & conclusion

The flight crew will require airborne surveillance and assistance for spacing or separation, i.e., an ASAS. The ADS-B concept of use is endorsed and AS/GS package I is supported –It introduces ADS-B surveillance including GS applications such as ADS-B-NRA, and AS applications such as ASPA-S&M and ATSA- SURF.

The Circular should be published soon. ACAS is reaffirmed a last resort system independent from ground systems but impacting the ATM system.

SCRSP/1 report proposed SARPS for ADS-B on 1090ES. Historical ANConf/11 ASAS implementation guidelines Required Surveillance Performance ASAS concept of use Perspectives & conclusion

SCRSP/1 (Nov.04) produced a framework for the development of RSP addressing surface, air-ground and air-air surveillance.

ASAS concept of use should provide a consolidated view of how ASAS applications would be a component of the ATM system. ICAO panels are progressing based on State’s expertise and contributions. ASAS-SG is open for additional views and ideas to progress faster on the subject.

The requirement to ensure system interoperability will also fall to industry, leaving ICAO to concentrate on functionality. The change results in a three-level hierarchy of requirements and specifications for complex aeronautical systems. –At the first or "core" level, the ICAO standards and recommended practices consist of broad, high-level requirements contained in annexes to the Chicago Convention. –These SARPs are augmented by technical specifications which are published in appendices to the annexes. –Lastly, the related detailed technical specifications will appear in separate documents published by ICAO or other organizations.

For ASAS applications, will RSP and PANS be sufficient to derive architectural solutions? We hope so Standards before the system? Mode S SARPS in 1997 and Mode S stations in Systems used then standardized? TCAS existed then ACAS was standardized.
