Please use proper capitalization. It makes my eyes hurt less. I know what FOV stands for, I was just wondering if that particular parameter could be used on something else.
Do you know what it is? If you do then I am sure you will pardon me for assuming you didn't when you mentioned it, esepecially when used in the context you suggested. Max fov would define the maximum horizontal viewing angle for the player datablock. For all intents and purposes this defines the maximum amount a player can "zoom out." It's not exactly zooming since you start to get a squeeze effect at high angles. It has nothing to do with the top down effect nor would it be of any use in a radar effect.
As for typing in caps, sometimes I do, sometimes I don't. It depends on the mood I'm in. If capitalization manifests in physical pain you should see a doctor. In the future I'm not going to modify my posting behavior to accomodate your unique condition and you should be prepared for some severe eye-pain.
