Autorotation Vs Airplane Mode Glide
I have no doubt that the V-22 has the ability to establish an autorotative descent. The report provided by SASless clearly states that, “that the probability of a successful autorotational landing from a stable autorotative descent is very low.” As a result the manufacturer implies that the recommend method of landing with both engines inoperative would be an airplane type glide to a touchdown to a hard surface. SASless, it sounds as it 30% is the best one might see. From my perspective nearly 100% of the time a viable autorotation is not a choice. An airplane mode glide to a touchdown gets my vote as the procedure of choice, if for no other reason than that it will provide a little additional time to sort out the situation while inroute to the mishap site.
