Thanks everybody,
I am now wondering if i might have got things mixed up with SH3 GWX.The charts show how far you will travel in X hours at X speed.Has SH4 ever had anything like this? (O dear,my old memory)
Anyway i have found pdf versions of these charts,problem is i believe they are copies of the ones used in GWX and therefore are in Km.so will need to convert to Nm
all the best-now go sinkem
