Welllllll,..... I actually got tought that technique by my instructor back when I did my Hu500 transition ....he was one of them Ex US Army Fort Wolters/ Mineral Wells IP guys and I gotta tell u IT WORKS .....its the old Airspeed for Height trade and you don't need to be at 50' agl to use it ....done well it means U can get into Autorotation without losing much height at all AND/OR U can use the technique to recover Nr if things have turned out a bit wrong!!! ....but U better have your wits about you when U do it!
