actually human eyes' fov is little more than 180° on the horizontal plane, with the external area that works better than the inner for nightvision, but has problems discriminating colours and has also a very low vision quality, since vision get more blurry the more you get close to the limits of your fov.
I stand corrected, that's what you get for posting last thing at night
Yep, I think an approx area of about 120% is probably about right, and I know I've said this a few times, but I still think it would be good to have...
1) Tactical view - Setting of 1.0 - Can't shoot much, but can see plenty.
2) Standard view - 0.75 Can see less, but targetting is easier.
3) Intercept view - 0.50 Poor viewing, but exceptional spot-targetting.
Even modern fighter HUDS have this capability to a certain degree.
