z  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.    As the 
situation is different from any actual ship 
maneuvering, set values with large margins to CPA 
Limit and TCPA Limit.

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. 
The ranges of course and speed to be entered manually:
