At this point, both sides are lobbing unguided rockets essentially like artillery. If they felt they could get any closer/higher to allow precision targeting, than they would.
In the case of the Ka-52, they do have ballistic computers which allows them to calculate the angle and release point of the rockets to blanket an specific area. You can even see them on the HUDs videos.
The Ukranians with their Mi-8's are indeed eyeballing it, though.
