Quite a bit off the track here. As far as i know a subsidiary of ours was certified to fly the curved RNP AR approaches into Innsbruck and Salzburg with their E190, same as we did with our 737-700s. Whereas our A320 fleet is still not certified for anything below RNP 0.3 and is not RNP AR capable. Not no mention that the autoland crosswind limit on our newest just delivered A321 is still only 20 kts, which is even less than our 10 year old 737s who can do 25kts in fail operational approaches.
Quite honestly, the E-Jets are pretty nifty with their autoland capable autoflight system, even more so if equipped with the dual HUD setup.
