Simulator
Vision
Resolution:
A typical human eye is stated with a 'visus' of 1.0 for a far object, near field resolution differing. This gives a resolution of 2 to 1 arc min (2'..1').

Brightness:
Some common lux-values:
sky clear, sun 90deg130.000lx
sky clear, sun 60deg (high noon europe, summer)90.000lx
sky cloudy, sun 60deg (high noon europe, summer)19.000lx
shadow in summer10.000lx
office desk500lx
candle1lx
clear night sky, full moon0.3lx
clear night sky, no moon but stars0.001lx
cloudy night sky, no moon, no stars0.00013lx

Projector arrangement:
Projected sight shall cover the entire angle of window-sight, as it is important for visual approaches to have the field in sight. So the lower end for the situation when the aircraft is "almost" over the field, side-backwards during traffic patterns when the aircraft position needs to be judged having the field far behind at the side and finally the upper end of the screen at the sides, when turning in traffic patterns).

center of gravity is assumed at the throttle quadrant, as the cockpit is symmetric and
beeing the middle between overhead, MIP and central pedestral. CoG of the seats may also likely be at the level of the tq.
