That's pretty much the conclusion that I came to; you can design faults out of a system, and if possible you should (and in this case that seems completely possible), but you also need training for any that remain.
Maybe I should point out though that while I asked about this topic, I'm not actually rated on the Gazelle, so maybe it is covered in the type training. Was just it included the word 'stall' - something not generally considered to be a good thing in aviation - I just wondered if it would be applicable to any of the types I fly.
