What is an Aspect?
The aspect of a target is the relative bearing of the own vessel from the target (or the angle between the target’s course and the theoretical line of sight), expressed in degrees between 0º and 180º Red or Green.
Knowledge of the bearing of a target from the own vessel and the aspect gives an idea of the angle of approach between the two ships, which is necessary from the ROR point of view.
As per the example below aspect is 45 degree to red.
