I think this
is rubbish !!! reducing power down to auto level is part of any steep descent and your insurance co doesnt need to know about it ......do not confer on them intelligence and technical knowledge they do not have ........what they mean is no practice engine failures by yourself which is different . I have always advocated banning autos to the ground solely on the basis that people seem to ( yes mainly robinsons ....)mess it up regularly and this ends up on my insurance
If you want to do eol,s pay an extra premium or do power recovery which is just as good in my mind. if you then get a real one it really doesnt matter if you mess up the last few feet .
