YES , in RS , AS or ASAP



I have noticed that P Instrument (range boresight) work

----- Thats NOT the range boresight

----- It is the distance of thge target if it fly his course away from you .

------ P = 0 Km means: the target will hit you , it is of course to you.

----- P=12 Km. The target will flown awy with distance at 12 Km frpm you
