Including prop cones sounds fine. I'm not sure about the three inch limit though - one of the later B-52 experimental a/c had a long probe attached to it, that looked thicker than 3" but I'd be inclined not to use that as the reference point, but use the nose location on a standard a/c. How about the frontmost point on the leading edge of the main-wings at the root - or would that be snafu'd by LEXs? e.g. F-18. Could be a bit iffy on the AN-225 as well, now that I think about it, as the wing roots flare into the fuselage. Leading edge of the elevator?
