Not sure where you looked, but I just looked at the CAT II/III plated for LAX and ORD, and none of them had a DH associated with any of the CAT III approaches.
Time to make some clarifications in this thread. The post by Ekhard was not written clearly, but I interpret it as saying that LAX and ORD do not have a CAT III approach with a DH but EASA allows CAT III with DH. But then the same post says that Denver allows CAT III with DH. I checked the Denver charts in my Jeppesen manual and I did not see this at all. However, keep in mind that we do not all get the same approach plates from Jeppesen, so if anybody has different, please post. But, I suspect that the CAT III DH thing is only an EASA thing.

I think this CAT II landing approval without autoland may be what Horizon Air uses on their Dash-8-400 out in Seattle which subject to confirmation, is also, I believe, done with manual throttle. Concerning the requirement for autoland when doing a CAT II reduced visibility approach, this is not accurate. The ops spec I have says that autoland or HUD to touchdown is required.

We still have a DH of 14 feet. But, I am reading that from a company manual(which is always subject to being out of date), not official French CAA documentation.

I guess it's an Ops Specs thing but still curious as to why Cat3B No DH would be allowed in a company's Ops Specs for DEN and not for LAX, given that the capability exists at both airports?
This appears to be different than Jeppesen charts I have which show CAT IIIA or B minima for airports in the US. In EU, they only show CAT IIIA and in that case, a company specific page has to be referenced to see if there is even CAT III approval and for the CAT IIIB minima.

[quote=Rick777;9276617]It must be an opspecs thing. I live in Denver and have been based here and LAX well as flying into ORD hundreds of times in A320, 767, and 757. We used an Alert Height of 50 feet for Cat III approaches. It was not a
