Yes first I understand a turbo charged Enstrom can hover at altitude and isn't a hovering jump preferred by jumpers. Can an Enstrom gain forward momentum from 5k to 6k feet agl enough for a autorotation? I'm not talking about total and abrupt stop of the main rotors I'm referring to say a turbo charger failure or something less catastrophic. If it is an issue then I get the impression 30mph is acceptable by jumpers, but then again if something happens can an Enstrom gain 30mph to enter autorotation if required?
