hi TheChitterneFlyer,
thanks for the quick answer, you are right for a 45/180 turn procedure it is as you say 1 min for A and B and 1 min 15 sec for B,C and D.
However I was more specifically asking about a base turn similar to the VOR 16 in RJFF or the VOR 17 in RORS. There is only a note to commence the turn within a specific DME but not given any DME when tu initiate the turn.
