False Capture:
I am not doubting your information, but here in Toronto, we fly CAT II approaches to an autoland on RWY 06L with a DH that is 100 ft above the threshold height. As there is a valley short of the threshold (where two large aircraft have ended up over the years), the actual DH used in the FMS is 108 ft. The valley is actually deeper than that (probably 30 ft below threshold height), but is rising back up at the DH point. Is the valley at MAN deeper than that at the DH point?
