Let me correct a little Gezahu's last post:
"текущая дальность" - current distance
Cobra, I believe some explanation is in order concerning this line from page 132 of the manual
"When in automatic mode, the ASP will draw the pipper according to either Sapphire data (if the airborne/ground target is radar-locked), or pre-set distance, target size and angular corrections that enable optimal use of ASP sight".
Or you could ask Novak to leave some comment on the way airborne gun targetting works and how the radar takes part in the process.
