And with the AS350B3e and EC130T2 the FADEC controls all. If you try to select ground idle in flight with the collective still 'up' it wont let you, it carries on (after a short blip) in flight mode. You then can not re-select ground idle, you have to shut the engine down in flight idle to reset it. You can only go to idle with the collective (almost) down first.
Hmmm.. not sure about that. I recently conducted training in the B3e and for autorotations the throttle could be woulnd back to idle and then re-advanced for power termination. I know the "throttle" in the B3e/130 is actally a switch that selects from idle to flight and vise versa as opposed to an acutal throttle al la 206 etc. before I get flamed.
