@changer, the 737NG and 787 can do it all using the APProach mode, older 737 still have to use LNAV/VNAV, and of course if you are equipped to fly other than ILS precision approaches, for example GLS (standard for the last 5 years on our 737s) or MLS, there is no LOC/GS to connect to in the first place. It's called IAN and provides a FMC generated localiser and glide slope alike presentation for NPA approaches.
galaxy flyer, true or not true depends entirely on OPS specs of the operator and state approval e.g. AIP. FAA does allow the nav aid to be u/s EU OPS doesn't, as simple as that.
True, however EU OPS does not require that it is displayed and monitored. Might be a special approval since we used that allready back when JAR-OPS was current and it is now grandfathered in, but i seriously doubt that.
