I strongly agree with Lomapaseo at dash 289. If either one fails,autofeathers,and just lets You just know about it,just fly the plane. It has speed,it is climbing,and not much to do for the failed one right now. Later,when alt and situation permits,you may turn your attention to something else. Sure it`s a lightshow with perhaps guiding vocals,-but who would care less. If it flies and climbs,that,s all there is to think about. All the World`s time later on,to think and troubleshoot why it did that.
