Tracer-15, the trick is that each view direction can be altered and saved for each seperate aircraft. Besides your regular "look forward" (when you don't touch anything), you can also assign a head position for when you look forward with the numpad8 key (or by use of a hat switch). It is this "alternate" forward view that are being used for the special sight.
Besides things like this dive bomb sight, it is extremely helpful when you want to achieve best visibility in a certain direction, instead of looking straight into a cockpit-bar.
Problem is that each plane has 27 views you can program (more if the plane has gunners), so it can be quite a work to optimize all the different views for all the planes.
However, the headpositions I use I have made available for download at my site. I also set the view through the sight in the 'val', but didn't knew that it could actually be used for anything.
