I was thinking about this the other day, too, but from a different perspective. Still, it might (at least partially) address Hook's desire.
Currently, the Aitport Info page has the outline of the runways inset in the lower-left corner, with two links on that figure: "Show on Map", and either "Airport Diagram" or "RealView", where "Airport Diagram" is presented if one exists and "RealView" is presented otherwise.
While I normally want to see the Airport Diagram instead of the RealView if one is available so this UI approach works for me most of the time, there are occasions when I want to see the RealView instead, so it would be nice if both options were available.
One way to do this would be to always put "Show on Map" in the lower left, always put "Show RealView" in the upper left, and then, when an Airport Diagram is available, present that option in the upper right. That's a deviation from current behavior and might initially be surprising to users who are used to seeing the "Airport Diagram" option in the upper left when it's available, but I think it will be intuitive/obvious since it will still appear nearby.
(Didn't this inset used to work something like that in the past? I want to say it used to be that if you tapped in the top part of the inset, you got the Diagram, and if you tapped in the lower part, you got the RealView, or vice-versa...)
