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

Note:
  The trial maneuvering function is available only when a target tracking unit (option) is installed. 
 
 
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 are as follows: 
 
Course: 360° (in 0.1° intervals) ........................................................................... [EBL] dial 
Speed:  0 to 100 kn (in 0.1 kn steps)................................................................... [VRM] dial
