Bat-Off may I suggest like the others that you put down the glass of Champagne and the little Budgie book and trot off to a competant flight instructor to learn some helicopterisms.
The Agusta A119 has an IAS in auto of 80 kts which following some rigorous testing turned out to be 65 kts actual airspeed, so what you see on the ASI is all that you have and have to use it. B47 autos were taught by the Army Air Corps at Middle Wallop as Flare Auto, Constant Attitude, Zero Speed and Hover Auto. The Constant Attitude was taught to be used at night as the landing light was fixed and as soon as the ground was seen in the landing light the collective was raised to cushion the landing giving a minimal run on.
