I missed ?
I hit where I aimed
Its simple 270kph ias @ 3900m = TAS 330kph whats wonder woman TAS got to do with anything just use the bombsite table settings and it works
The bombs dropped in the center of the target that's the way I use the sight and have for years the TAS is correct that's why I hit the middle of the target.
The point of aim is between the 0 and 5 indicator 2.5 being the target center.
NB
All consideration taken from actual pilots using these crude bombsites back in WW2 we do better than they probably ever did,
they were never designed to be precision bombing devices just a general aiming sight.
