Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

I refer to the draft ASO Report on the traffic confliction incident involving Beech 1900, VH-IMA, Beech 1900, VH-IMH, Piper PA-31 (Chieftain) VH-SVV, and De Havilland DHC-8-201 (Dash 8), VH-TQO, which occurred near Port Macquarie, NSW on 28 April 1999.

The Civil Aviation Safety Authority does not agree with recommendations R20000181 and R20000182, but supports recommendations R20000184, R20000198 and R20000199. R20000183 is still being considered.

I am concerned that in making the recommendations contained in R20000181 and R20000182, the ATSB has not recognised either the limitations of ACAS equipment or the fact that such recommendations cannot be justified on a cost-benefit basis. A detailed report on this aspect of the incident is attached, which has been prepared by the CASA officer who is the current Australian member of the ICAO Secondary Surveillance Radar Improvements and Collision Avoidance Systems Panel.
