'Upset recovery training' in the sim is a tick in the box requirement every 3 years in refresher training. If it wasn't mandatory I doubt any airline would do it. Instead their attitude is to have rigid SOP's that should keep you so far away from such possibilities that the risk is negligible; so why train for something like that? They don't even teach their guys proper basic manual flying for visual circuits, other than base training, and then the door is closed. So don't expect any enthusiasm for any extra upset recovery training. They don't even refresh basic stall recovery or training about the known 'gotchas' of some of the automatic systems.
