2.26.5 Setting vector attributes (ARP)

What is a vector?

A vector is a line extending from a tracked target which shows estimated speed

and course of the target. The vector tip shows an estimated position of the target

after the selected vector time elapses. It can be useful to extend the vector

length (time) in order to evaluate the risk of collision with any target.
