HF - you could either ban all automation, but that would put us back into the accident regimes of yesteryear, or ensure that your crews are fully aware of its behaviour under different conditions, know the pitfalls and have well thought-out SOPs for its use. I prefer the latter approach. Also its a good idea to have automation where the pitfalls are plugged, such as in the 225.
But in this case IF, (and its a big IF) it was as we describe, the fault was a failure to monitor, not an inability to fly.
