PVI-800 coordinates at sealevel

[MarcT-NL]

This is probably not a bug, but "correct as is". But I still would like to bring it to attention.

When you manually enter target-coordinates in the PVI-800, it assumes the target is at sealevel. Which it almost never is of course. That could be explained by the PVI not knowing groundlevel at that coordinates, like the ABRIS does. That could also explain why the ABRIS shows the correct location of the target, even if the Shkvall can't slew to it. It slews to that target at sealevel.

However, when I use the Shkvall to get the coordinates into the PVI, the Shkvall is spot-on. It will slew to the target's exact coordinates at groundlevel in stead of sealevel. This also could be explained because the PVI-800 now can calculate the altitude of the target. It knows its own coordinates and altitude AGL, it knows the angle the Shkvall is looking down and it knows the range to the target (laser). Simple goniometry could calculate the hight of the target.

When you compare the coordinates that you entered manually with the coordinates of the same target obtained by the Shkvall, they are exact the same.

That must mean that the PVI-800 CAN considder altitude. There is just no way to enter that altitude manually is there ? Did Ka-50 pilots not complain about that ?  Will this maybe be different in the Blackshark 3 ?
