RUT LOC/DME 19
The DME is required.. and in this approach the DME is co-located with
the localizer for 19.


RUT LOC 19 (with DME)
DME optional, but the DME for use in THIS approach is co-located with
the VOR which is on-field, but sited differently from the Localizer.

I GUESS it gives you the option of using either DME if one happens to be
inop on the ground. the DME mins are in the 800 ft range agl (with
plenty of tall obstructions within 10 miles..) Might make it a little
easier for the commuters to get in there when the weather is bad.. I dunno.
