F=2*atan(w/d/2)
w - screen width; d - distance from viewer to screen; F - in game FOV for 1:1 scale; Setting FOV according to this, you will get real life sized objects on the screen, however that FOV will be too narrow for adequate SA in most use cases (i.e. using average display at normal distance).

give the man some el primo cubanos  to translate it into plain english: - if you use a FoV that is to wide for your display, all ingame objects will shrink in size compared to what they should look like in real life (but you gain extra peripheral vision). conversely, using a to-narrow FoV for your monitor size will artificially magnify all ingame objects (and simultaneously narrow your peripheral vision). - using the correct FoV will allow all ingame objects to be correctly displayed in size, but your ingame peripheral vision will only be as good/wide as your monitor is wide (if you then want better SA, get a larger monitor or consider using multiple monitors). if the game is coded/programmed/designed correctly you should now be able to spot all distant aircraft (or ground objects like trucks/tanks) from exactly the same distances as you will be able to see/spot them in real life. you can then briefly still snap to a narrow view for more specific aiming, or briefly use a wider FoV during a dogfight to improve your SA (but it will distort your sense of distance and speed). if you want to experience the virtual ingame CoD world "correctly", and see all in-game objects in their correct sizes (which will affect your sensation of speed and perception of altitude as well etc), you MUST be using this "correct FoV" setting most of the time while flying around if you then still cant spot that distant aircraft at 1000 or 1500 m (which you would be able to see/spot in a similar real life situation) then there is an error in the game where these distant LoD models in CoD dont stand out enough (or contain errors, like some of the old spitfire lod models in the original il2 series which had missing wings etc)regarding viewing distances, be aware that most pc gamers will sit with their eyes/head at roughly an arms length from the monitor on their desk (in comparison, for users of large displays like projectors and large lcd tv, on average they will sit at a distance of 2x the height of the screen ). to get the needed variables to calculate your "correct FoV", measure the approx distance from your eye's to the monitor (used during game play), and then measure how wide the monitor display area is, then use the appropriate formulae to calculate the exact FoV figure it represents, and then simply set the il2 game to that wide setting. for those who have problems spotting/seeing/tracking nearby or distant aircraft (or ground targets), this should be a significant help. it will also reduce the problem of the disappearing LoD models for most (unless the game contains LoD model design errors) note: if you use a trackir, it is pretty amazing to see how the gunsights in CoD are correctly modeled to allow 3DoF and the gunsight reticle functions correctly as it would in a real cockpit with you leaning forward/back
