It's dosn't work like that, changing the field of view does not bring your hand closer, it is like looking threw a zoom lens at your hand , then adjusting zoom. What is in the back ground will not move as compared to your hand by zooming a lens.

I hope you see this as a discussion. Not as criticism. What ever AH3 uses I will still play the game. Newbies just need every break they can get.
I must have used a bad analogy but the front frame size appears to be larger at 80 FOV than at 90 FOV as seen on the screen if you use the same head position. A measurable difference in size. Much like my hand example where your hand looks bigger as it gets closer to your eyes but the hand is the still the same size. Now why it looks bigger? I bow to your expertise.
Now if there was a single FOV setting for everyone, then this post becomes mute.
If a red is flying across the frame then no big deal but if the red pulls up, and you pull up to set up a shot, the chances of the red icon being hidden by the cockpit frame is greater at 80 FOV than it is at 90. Again, this is using the same head position in both FOV settings.
