13. TRACKED TARGET (TT) FUNCTIONS
13-5
Relative vector
Relative vectors on targets that are not moving over the ground such as land, naviga-
tional marks and ships at anchor will represent the reciprocal of own ship's ground
track. A target whose vector passes through own ship is on a collision course. (Dotted
lines in the figure are for explanation only.)
To set the vector, click the vector time and vector reference indications in the [TT/AIS]
page to set them.
