Yes, I talked to a chap from d.a.p. (Howard) at Cranfield. It's part of the program to reduce cas busts. The idea, I think, is to put the photos & notes on the caa website so if you're, for example, going through the Machester/Liverpool low-level corridor, you can review and print off pictures of the navigation points. I've been to Barton a couple of times, but I never knew what Thelwall Viaduct looked like until I saw the pic.
Having used the Oz VFR guide for the Bankstown area, I think it is a very good idea indeed. If you agree (or if you don't) tell the CAA, they want feedback.
