I try to get into the sim with perhaps the most simple of the systems as far as I noticed. I tried to engage a B52 target drone which have both dm and cm jam equipment. I accuire the ep and beta as told in the manual and I assume it's range using the tables in "A" view and I use the bore sight control in order to move the range line into place but I can't "lock on" (press the right mouse button in the R area) and therefore there is not envelope or any sign for firing the missile.

I saw that in the Volhov you can set the height of the target manualy which solves the problem. but how do you do it in the Dvina?
