FOV settings

[McFeckit]

Ok, I've been following this with great interest but I'm a little confused. I have a 19inch monitor (LCD) and I sit approx 1m from the screen. What FOV should I use to render the world 'real' as in what I would see if I was sitting in a spitfire in real life?

I simply want to see the world as a real spitfire pilot would see it....so which FOV should I use?

Excuse my ignorance but it would be great if the intelligent guys here could help me achieve this.
