Abstract:

In any parallel indexing technique, the intended track of a ship in relation to a radar-conspicuous fixed target (reciprocal for relative motion, "parallel" for true motion) is plotted in advance on the radar display. So are traffic separation scheme limits, margins of safety, wheel-over positions, relevant nav marks, and other data. During passage, the display is carefully watched for any departure from the predetermined navigation plan. Deviations can be seen surprisingly simply, and early; the appropriate corrective action is indicated and can easily be taken. The radar indexing technique depends heavily, of course, on the existence of good, reliable radar-conspicuous fixed points, readily identifiable and accurately charted. Otherwise, the system is well within the ability of the average and otherwise competent deck officer to learn and apply. It does not require simulator training, but there is no doubt that a bridge team course is by far the best way now available to teach the method.
