an IFR approved aircraft must be equipped with at least 1 DME, from what I remember, that should clarify the presumption.
I always presume the lowest denominator with hypotheticals like this one. A not-for-hire airplane in the U.S. does not have to have any airborne DME to fly IFR below FL 240.
It may be different in Italy. But, if so, why did they include the non-DME minimums for VOR 18 but not for VOR 34?
In any case the VOR 18 requires the LIN 5.0 DME for the missed approach so the designers screwed this one up.
