yes the cockpit view would be spread across the screens. you would need three screens, of preferably the same size though.
if you had an i mac 27" and two 27 displays it would look good, but if you had an imac and a macbook pro, i reckon it'd be all but unplayable!
you really need a minimum of three monitors for multiscreen playing, two screens even if they're the same size really doesn't work as you wouldn't have a left view, central view, right view effect, but a half screen left and half screen right with the monitors bezel being right where you targeting reticule is.
