Crashworthy Seats
Not sure what a zero/zero autorotation was as referred to, but if one has a video of a zero groundspeed auto landing in the 225-AT MAX Weight, I'd love to view it. Also, with re to the S-92 float deployment question, that procedure was the subject of lively discussion, without unanimity of opinion ( but finally, with consensus ). Note the section of the flight manual that covers the inadvertant flat deployment speeds etc. We flew all of that, of course, and there were no flying or handling problems at all. Biggest excitement was the sound associated with deployment.
