True Vector Mode 
 
In the true vector mode, the direction of a target vector indicates the true course of the target and its vector 
length is proportional to its speed. 
In this mode, own ship’s vector is displayed as shown below. 
In this mode, the movements of other ships around own ship can be accurately and easily monitored. 
However, CPA Ring cannot appear in this mode.
