OK, Meekal -,that's a little clearer, but if you read the thread from #1 you will see that the suggestion is that the a/c broke right OFF the R30 ILS to circle for 12. No-one except for you has mentioned any 'procedure' for R12 - I have asked. It might help if you post any chart you have? But even so I cannot see how you can have a 'circle-to-land' based on a DME arc since it is a visual manoeuvre?
