I used to do a bit of teaching in the 20 and 22, and tend to agree with the general trend of the thread.
5 hours dual does seem a little much, but insurance requirements and insurance requirements! I suppose different companies have different premiums etc.
But that being said, I have seen and heard (like VH-XXX) of people getting into some trouble due to a lack of understanding of the displays/electrical systems. The plane itself is pretty straighforward to fly. Remember most poeple learning to fly the cirrus, have generally only a PPL, with the majority of experience on 172s and arrows etc. Most of these would not have had Garmin 430s / fully couples autopilots and integrated display screen, so in some respects it is new.
That being said, using the CD and a decent instructor, an average pilot should be up to speed well within 5 hours.
