I am going to be shouted down over this.
Flying single-engined helicopters in Borneo in the sixties the choice of landing sites was somewhat limited if the engine packed it in. To reduce the percentage chance of arriving in 200 ft. high trees one went for the range autorotation. Should the engine stop than the Rrpm was allowed to decay to just above minimum controllable and the airspeed kept at the cruise. When (or if) you found a suitable landing area you flared at the appropriate time and took your chances with the undergrowth.
Otherwise you flared at the appropriate time and took your chances with the trees.
