@defacto: we are encouraged to fly raw data approaches whenever we feel like it. On the 737 around 60% of my approaches were flown that way. However, if we do elect to use the autoflight system for even a part of the approach it is dual channel, even if we switch it off at 2700ft (usual platform altitude here is 3000+). Makes it much easier to fly a missed approach if one becomes likely as the autopilot remains engaged, unlike with a single channel approach. And flying a missed approach in places like for example ZRH is probably not the best place to show my superior flying skills but rather to show my decision making by using the available means.
