First and maybe last flight lesson
If the instructor on the ground told the unlucky student to push the collective down and enter autorotation, would that add any stability?
Some airplanes will come down in a wings level stabilized sort of mush if the horizontal tail is deflected to an extreme angle. NASA did some work in this area, also models and UAV's are landed this way without pilot input.
Gliders sometimes stay wings level with the dive brakes open and the pilot releases the stick. Good to know when you are sucked up into a cumulus without instruments.
Does anybody know if autorotation is more stable than powered flight?
