Thanks for the reply.
The DME is referenced to initiate a turn, thereafter it's headings until you're almost over the next NAV.
Again, this same OEI flight path has been in use for over 30 years for the takeoff and over 10 years for this miss. Had they questions about the NAVs obstacle clearances along the path, all they had to do was ask the operator and the obstacle analysis vender. Instead it was simply denied because the OEI had not been "approved."
