Safety Recommendation

Pilots should recognise that they cannot rely entirely on vision to avoid collisions. Consequently, they should attempt to obtain all available traffic information, whether from Air Traffic Services or a listening watch, to enable them to conduct a directed traffic search.

Initial response
Date issued: 29 April 1998
Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

CASA agrees with both the above recommendations. However CASA believes that the limitations have been promoted to the extent that benefits of the visual system may have become seriously discounted. As a consequence, CASA will continue to emphasise the requirement to be vigilant.
