A dumb question, The guns are fixed to the airframe?
To change the aim point the heading and pitch are changed?
All this by the input of the helmet position?
With the target moving, the helmet must track the target?
Very complex.
Gun remains fixed, JHMCS helps identify designated targets.
For the Apache helos, the guns are slewed to where the gunner is looking. For fast CAS jets, a gun will not be slewed.
Hardest part is seeing the target when you are moving fast.
