If your target is moving in a straight line (hasn't detected you yet), your PK has to be activated, then you need to enter the speed AOB and range using the data entry interface in the upper right corner of ur attack periscope screen. Once you establish a setting with the 3 instruments that interface has, you must send the data to the PK by pushing the red button with triangle on it (it's at about the 11 o'clock position on the on the stadimeter,AOB, and speed entry interfaces) once that is done the PK will then Keep and Track the solution relative to the vector components you just entered. you can tell if ur PK is working by going to the attack map. if ur moving target is represented by an X with a line going in the direction of movement, you've entered the 3 parameters correctly and have a good solution (if ur data was reasonably accurate). You don't have to actually be using the periscope for this to work, it can be done with fancy sonar work and lotsa marks on ur navigation map with the various tools that are there.
