Limitations of the See-and-Avoid
Principle
The following recommendations were issued as part of the BASI
Research Report - "Limitations of the See-and-Avoid Principle",
1991. At the time of the issue of that report the six
recommendations were not assigned formal recommendation numbers. To
facilitate publication of the recommendations and the responses to
them, they have been entered into the OASIS database. As a result,
the recommendation numbers assigned to them do not reflect the
actual recommendation issue date, rather the date that they were
entered.
Safety Recommendation
In light of the serious limitations of the see-and-avoid
concept, the CAA should continue to closely monitor the
implementation of TCAS in the US and should consider the system for
Australia.
Note: The Recommendation was issued to the [then] Civil Aviation
Authority (CAA) in 1991.
Agreed and will be introduced where cost effective.
