Thanks! Indeed it is so but coming back to the point your AP/FD is not capable of tracking GS and therefore it becomes LOC approach with minima of higher than ILS. If you fly raw data it will be ILS DA which is lower albeit with higher RVR of due manual flight.
This isn't correct.
If you were intent on using automation (in this case the FDs), you could just follow the raw data (G/S) using FPA or VS. Until you put the gear down, you can do this with the AP on. Afterwards, the PM would presumably make the required corrections to keep on the G/S. The relevant minimum would be CAT I.
Personally however, I find it far easier to just go FDs off.
