But, if so, why did they include the non-DME minimums for VOR 18 but not for VOR 34?
because VOR 36 requires LIN DME as noted on the briefing strip. Without it NO VOR 36 is possible.
MAP for VOR 18 is LIN VOR itself I don't see where 5 DME plays any role in determining MAP? Care to elaborate? Thanx.
