At BMI British Midland we add 50' to the MDA. We also fly circling approaches (eg Nice). Had to do NDB's at Stuttgart (although the beacon is so bad we usually end up doing it visually). On the Aerad (Thales) plates we have a vertical profile corresponding to a 3 degree glideslope - PNF reads of the next check height for every mile down to MDA. BMI reccomend full use of the automatics, and it is tought that you use the autopilot (in HDG Select and VS) down to when you are visual. This is due to the high workload involved.
