Response text:

Before responding to specific recommendations, the following general comments are offered.

As a result of the survey, BASI has made numerous recommendations to airlines and aircraft design authorities as well as CASA and Airservices. Some seem to be rather utopian, in that they may be beyond current capabilities in automation. Nevertheless, it is important that perceived deficiencies are documented and that the various agencies concerned are alerted.

As far as the recommendations made to CASA are concerned, I am having
difficulty as to CASA's ability to come to terms with some of the fundamental problems identified. One of the drawbacks of CASA's move more towards an auditing function is a lessening of the intimate knowledge that we previously had of particular operators. Further, as the CASA legislative framework moves towards less prescriptive legislation, it may be more difficult to manage to the degree suggested in some of the BASI identified issues. The content of simulator exercises along with the detailed qualifications and recency of instructors are examples.

Recommendation R980030 "The Civil Aviation Safety Authority review the minimum standards for the quality of information provided in FMC data bases with the aim of eliminating. FIVIC data base errors".

CASA shares BASI's concern at errors in FMC data bases. However, since the industry standard is based on an ARINC Specification, there is little scope for changes to data format. As to data accuracy, we will pursue this matter further, noting that there is little point in mandating a standard which cannot be effectively policed. Since the provision of data bases is invariably contracted by the airline, it may be appropriate for CASA to specify that agreements between operator and service provider be part of the operator's approved quality assurance program, and therefore subject to regular CASA audit.

The Authority undertakes to keep BASI informed of progress.
