I guess this means a Category D is prohibited from using the LOC/DME-E, period. Correct?

Or was it allowable for a Category D to fly the approach to DOYPE (7.1 DME at 11,700) and proceed if they saw the runway?

Aircraft Approach Categories:

An aircraft's approach category is based on 1.30 VSO or VREF, as defined by the certification rules applicable at the time that the type certificate was issued, computed at the aircraft's maximum certificated landing weight. Transport airplanes type-certificated after December 2002 define final approach speed using the term VREF, which was newly added to the definitions contained in 14 CFR part 1. Prior to December 2002, final approach speed for transport airplanes was defined as 1.30 VSO.

Whether final approach speed is defined as 1.30 VSO or VREF, the aircraft's approach category is always based on maximum certified landing weight. It is never permissible to use a lower approach category based on the aircraft's actual landing weight. Non-standard landing configuration or abnormal procedure speed additives may result in the need to use minima associated with a higher approach category. If these lines of minima are not published, then circling approaches are prohibited.

Aterpster says "That approach doesn't have straight-in minimums for any approach category nor does it have circling minimums for approach category D. So an approach Category D airplane cannot legally even begin that approach" and I believe him. Nor does any other instrument approach for KASE have minimums for Category D, so doesn't that mean that Category D aircraft are prohibited from all but visual approaches to this airport?
