I assume that the said dot is at the centre of the wind screen..
also assume that the pilot is sitting at the normal eye height....
ANY AIRCRAFT....
look at it this way............
If you black out your wind screen leaving just a dot in the middle
THROUGH WHICH YOU CAN SEE.......
and if asked to land it on a r/w in cavok cond.....
can I assume that one can manage it with reasonable accuracy...
if you agree then what you are doing is nothing but keeping the dot on the target.......
