Hi,
well according to me..I always keep the thing simple...This means that if the title of the approach plate is ILS/DME..you need both system to work 100% to be able to shoot this approach..and this in respect of the stated minima..
This lead me to the rest of the question...if any of the system required is not available..specific minima must be stated..w/o dme >>> or G/S out>>etc..
hope this help you a bit...
