I knew Geoff and I do not want to upset any friends but something to consider here is time on type...
I have got like 4000 hours on the 139 so I know if you want to take the controls and fly manually a recovery from unusual attitudes or just to prevent a cfit scenario, you need to be proficient, once you press that force trim release button it becomes really sensitive...
I also have seen in the sim a captain that did not fly the 139 recently just going inverted and crashing into the runway trying a go around manually...
