    Your first sentence is wrong. Stop explaining things you don’t understand yourself.

      It’s a fact. Helicopters in general do not have the ability to glide to a landing, they can auto rotate if the rotor is still moving and has enough momentum. If the rotor stops or detaches helicopters fall…

        “if the rotor stops” luckily in this universe we have conservation of motion so the rotor doesn’t typically stop in flight

        Sure though, were it to detach the helicopter would fly like a brick

          Hubris isn’t looked on Kindle in the aviation world.

          Not common doesn’t mean not possible, we teach autorotation for a reason and it’s not because everything happens perfectly and every aircraft is perfectly maintained.

          Helicopters crash constantly and just as an fyi auto rotation is falling with style and so is glide.

          Like I said helicopters just fall, an aircraft in the most extreme engine failures tend to be able to glide effectively helicopters can never count on that luxury. So I dunno, since you agree maybe hop off the high horse and apologize.

            I’m terribly sorry that I pointed out conservation of momentum in a thread where you want to imagine helicopter rotors can just stop. I know that reality is inconvenient.

              You are failing to ask him a question: how does he know what he’s talking about?

              His phrase was “we teach” which implies he’s an instructor. You should ask him if he is.

              Being wrong is the issue.

              Rotors can add have seized, rotor failure is actually one of the more common modes of failure in a helicopter. Also notably I didn’t say it had to stop just that the rotor is no longer effective, like catastrophic blade loss.

                You said helicopters “just fall” when they lose power. That’s what spawned this tangent. You didn’t specify anything about the engine being seized, which is an additional issue.

                You are moving the goalpost, and asked someone to apologize to you for it. You’re a clown mate.

                  Autorotation relies on one main thing, air being forced past a freewheeling rotor… Air that is being forced past because you’re falling.

                  Notice the immediate loss of attitude? It’s because they’re falling, unlike planes which can generally glide after an engine failure.

                  Specifically we’re speaking about helicopter ejection which in most cases means total loss of power or control or both. The only known helicopter eje tion seat(to me at least) to operate currently in modern combat is the ka 50/52.

                  One like this one which happens to eject and notably falls like a stone.
