ON AN AVOIDING METHOD IN RADAR NAVIGATION-PART 2

It is necessary for a navigator to know the present risk and the maximum future risk in the avoiding method in Radar Navigation and it is not enough to decide the present risk and miximum future risk with only distance between two vessels. The writers defined Admissible Time (A.T.) as follows: A.T. is the distance divided by approaching component of a relative vector, and considered the risk using this A.T. and distance. Accordingly the risk can be obtained and the risk is closely related to approach speed. When the approach speed is fast the risk should be represented by A.T., while the approach speed is slow the risk should be represented by A.T. and distance.
