In US style machines...
Stuck left....you are having a good day. Roll the throttle(s) off to the bottom of the green...shallow approach to a very low hover...either the aircraft will hover or as the nose starts to swing....land the aircraft and follow what turn if any with cyclic as you lower the collective. Chopping the throttle is a NO-NO on during this situation. Wind on right side helps.
Stuck right....not a good day. Regain manual control of the Nr...and set Nr in middle of the green. Shallow approach....maintain airspeed high enough to allow streamlining of the airframe......to a low height and align the aircraft with the landing area and movement across the ground....control the yaw with throttle movement. After touch down follow what turn occurs with cyclic. Wind on left side helps. Last ditch effort is an autorotation if need be.
Loss of tailrotor components....you are having a very bad day.
Enter autorotation....try to maintain pitch attitude....see if there is a power/air speed setting that allows forward flight (if time). If forward flight is possible...recover to a suitable place for an autorotative landing.
The outstretched finger works as a guide for throttle movement.
