Abstract
The earlier papers in this series described the principles, and some of the techniques, which determine the approach to separation standards made at the Royal Aircraft Establishment. In this approach to the problems of estimating safe separation standards and specifying the quality of navigation needed, emphasis is laid on the observations of flying errors which occur in operational conditions. Dependence on theoretical assumptions is limited to the extent necessary to make usable ‘upper limit’ estimates of collision risk. Where critical assumptions are unavoidable, their nature and effects are shown.
