The fighter's melee modes allow it to aim the missile at the target within the ILS (DPSR, ie + 12gr from the center of the HUD) or within vertical lines up to 45 grams. up in dir. VERT.I pilot needs to drive the target into this zone for what time goes. And with the help of the DDP the axis of the weapon moves along with the rotation of the pilot's head in the redistribution of the cone to 75 grams (ie, with the head of the pilot synchronously moving the missile, missile, ). The pilot does not need to be banned and drive the target in the HUD field, but enough to maneuver the head of the NSC on the target, the GOS will be captured (the indication of the CNS changes and the capture sound appears) and immediately starts (the BC usually already clamps) OLS or RLPK (which is unlikely) they will also be ut provide targeting GOS raket.Edinstvennoe condition all these disabilities angles missiles targeting (for P-73 so that it is the pilot's head will fall off faster than it comes out on the restriction of the rocket.) point O. In addition to maneuvering the capabilities of the aircraft, the full potential of the missile launch vehicle and the pilot is simply doomed to success.
