Here's another angle to it. Before ditching should you undo your seatbelts? High time pilots confident with their autorotation skills might undo seat belts before, knowing they can put her down gently and so not have to undo seatbelts under water which I'm told is not as easy as one would imagine. I've heard stories of people completely unable to get their seatbelts open under water. On the other hand if you make a mess of it and go in heavy, you'll probably wish you had your seatbelt on. My own opinion is keep them on, and after surviving touchdown pray you have the presence of mind to get yours and your passenger's (should he/she need help) undone. My instructor however seems to prefer the first method. Obviously has more confidence in his autorotational ability than I do in mine.
Any ideas?
