6.13  Trial Maneuvering 
 
Note 
Trial maneuvering is to simulate own ship's course and speed in the conditions that the course and 
speed of a target ship are unchanged as they are.    The situation is different from any actual ship 
maneuvering, so set values with large margins to CPA Limit and TCPA Limit. 
 
 
6.13.1 Outline of Trial Maneuvering 
The trial maneuvering is the function of simulating own ship's course and speed for collision avoidance 
when a dangerous target appears. When the own ship's course and speed are entered in manual 
mode, the trial maneuvering function checks if pre-acquired or pre-activated targets are dangerous.
