In-cockpit camera view?

I've been thinking about trying to write a gauge that presents the sort of view you see on real in-flight screens with some airlines (e.g. Saudia) where you see what's going in front of a plane during takeoff and landing from a nose-mounted camera. Well, I was thinking of trying to simulate that by getting an icon-controlled pop-up to show a defined view (say, nose-mounted camera, slightly pointed down) from the 2D panel without having to press W or go to the VC view (only if there's no acctual VC, of course).
Anybody knwo if there's one already out there (re-inventing wheels and all that), or what I might need to do to write one?
