It is interesting to note that there appears to be no recommendation to install an ILS onto 28, it may require a steep slope, or infringe obstacle limits, I don't know. At Stuttgart, prior to them lengthening the runway about 10 years ago, runway 08, as it was then, had an ILS promulgated as not for use, but it sure helped those NDB/DME approaches a lot. Surely something similar could and should be done at ZRH, especially as the late evening arrivals are on 28 as a matter of routine nowadays.
I believe that an ILS is being installed onto 34 now - about time, this place really does need sorting out, safety at ZRH really does appear to be a very poor second relation to the Zurich rich folks.
