First the head position is set up and down and forward and back to a real life position. It would not be adjustable. Then the FOV is set to give best forward view with an acceptable peripheral view. An acceptable peripheral view is one that covers the needed view when you look up or back as an example.
If zoom is used it too should be default set to compensate the limits of monitors as noted by Hitech and not be adjustable.
The more adjustments you remove from the game the less opportunity to game the game I would think.
And that default set to compensate for the limits of monitors would be slightly different between a 17" laptop and a 52" screen at the same resolution, wouldn't it? How would the system be able to tell? All the program knows is resolution.
How about a triple-monitor system? Not allowing people to adjust their view preferences is either going to completely hamstring the triple monitor setup or make it even more advantageous to have depending on which side you make best when you set the default.
The head limiting is something I've often considered. If I'm strapped to a seat with my shoulders square looking as far as I can to my rear, I've got about a 30-40 degree cone behind me where I'm not going to see much, much less be able to track and define the orientation of another aircraft. Our ability to sit in a stationary office chair and look dead six and up all day with no fatigue and perfect view is much better than it would be IRL, but it improves gameplay IMO.
However, at 6'2" I highly doubt if I were sitting in a 109 my head would be anywhere near the center of the view for the gunsight unless I hunched way forward, which would completely change the geometry of what I would be able to see versus what a 5'2" jockey would see strapped in tight and sitting in the same seat.
The Linda Blair effect and adjustability of views is, I think, a fair compensation for gameplay, differences in hardware, difference between a monitor and the Mk. 1 eyeball, and personal preference. It is certainly possible to gain advantages through equipment, but it's also possible to somewhat compensate for disadvantages and personal preference with the adjustability.
The HUD may let you better evaluate the dive angle you end up with but you actually set the dive angle to the target with the location of the start of your dive. There's no point setting a precise dive angle that doesn't point you at the right spot on the ground.
I've always done decently at jabo, not pinpoint accurate, but I can usually hit close enough with a 500lber to take radar or ords at least 3 out of 4. I've always been in the "that looks about right" school of divebombing, but it has seemed to me that more consistency of dive angle means more consistency of sight picture and impact point for the dropped bomb, isn't it? Varying your dive angle has a substantial effect on where you'd aim, doesn't it?
