US CAT II minimums?
I notice on the ILS Rwy 30L CAT II to MSP that the radio altimeter is not authorized. DA(H) then is at the IM for the RVR 1200 approach. No problem there.
The 1600 RVR DH is 150'. If you are not authorized to use the RA, and there is no marker, what is used to determine the DH?
Surely not the baro altimeter. (?) I've been under the impresion that the baro "can't" be used to determine DH on a CAT II.
Rwy 16R at Sea-Tac is similar.
