These systems actually hurt pilots. While at first glance it may seem to be a good thing to have the plane "save" itself, or level off as you say. But the downside is that pilots never learn to fly their own planes, and return the plane to level flight themselves. These devices teach pilots that when they get into trouble they should simply let go of the controls. So, if you start using one of these devices the chances are that you are going to have to continue using it simply because you never learn the skills that every other pilot learns with their trainers.

A second problem with these is that they do not always work. So if you use the above situation where you rely on the system to save your plane, and it fail your plane is going to be toast.

IMHO these devices aren't much more than a sales gimmick. Simply learn to fly a plane and you'll be much better off than relying on something like this. Plus, you'll get more satisfaction out of your planes knowing that it's actually you flying them, and not a circuit board.
