Corridor is R 45 S Jepps 2003. Parts of this corridor are surface +, the bit I crossed was 800+.
Your point about having military routes noted on civilian charts is very good, it gives us a chance to avoid them, provided an upper limit is stated on the chart!!!
It is not true that the RAF operate everywhere, they have designated low flying areas like French mil, which tend to be in unpopulated areas. These are just not shown on civilian charts.
But why the CAA can't at least publish military choke points on UK charts is beyond me.

Some useful sources of information you have suggested which I will refer to for future flights into deepest France! (which I enjoy greatly)
