ASAS TN Seminar October 2004 4 Where Are We Today? Good News: All aircraft flying IFR as GAT in Mode S notified airspace must have a Mode S Transponder (with Elementary and/or Enhanced Surveillance capability) by 31 March 2005. Most of these aircraft will also have 1090 Mhz extended squitter enabled to provide ADS-B data (ADS-B out). Not So Good News: The activation of 1090 Mhz extended squitter is not mandatory!

ASAS TN Seminar October 2004 5 Current JAA/EASA ASAS Activity JAA CNS/ATM Steering Group has studied the certification issues concerning ASAS and will make recommendations to Central JAA/EASA – see Position Paper pp009. Position Paper pp009 is a mature draft that provides an overview of ASAS developments and their implications. Guidance for the equipage standard for each ASAS application is being considered.
6
ASAS TN Seminar October 2004 6 Recommendations made to JAA/EASA - pp009 1. JAA should establish a specialist sub-committee to consider the implications of ASAS developments with the objective of developing operational regulatory and guidance material with attention to Package 1. 2.The development of the CDTI should be carefully followed with consideration of human factors, display symbology, flight deck integration, crew procedures, training and the likely impact on certification standards. 3.JAA flight crew licensing specialists should consider the impact on flight crew licensing standards that may arise from the implementation of ASAS applications.

ASAS TN Seminar October 2004 7 Possible Certification Issues Integration of ASAS with existing ACAS and TAWS Integration of Warnings and Cautions Human Factors Accident Data Recording of ASAS data Crew Work load System Architecture System Safety Assessment Compliance with Certification Specifications MMEL and Flight Manual
8
ASAS TN Seminar October 2004 8 Way Forward Complete the Operational Safety and Performance Assessment for both ground and airborne system. JAA/EASA to provide guidance for certification of ASAS functions on aircraft – this should address stand-alone and integrated solutions. Encourage voluntary installation/upgrade of: ADS-B ‘in’ and ‘out’ capability and Display of traffic information to pilots (When sufficient guidance material is available!)
