From what you describe, it sounds like we do not have enough information about the runways to map them in detail. Specifically, the threshold coordinates of the runways.

Hi all, just looking at planning a route and noticed that RAF Henlow, although showing as having multiple runways when zoomed out, when zoomed in only Rw 13/31 shows in the pictorial overview. The info tag does indicate it has four runways though, as does Pooleys. Is this a filtering setting I'm missing?

Ps this is on the iPad!

Any ideas?
