Many thanks for the replies!

Just to clarify, when you start the first engine, do you have to advance he lever to the flight position prior to starting the other engine allowing the battery to recharge or you start the second engine with the other engine in idle?
When you start the engine do you select the idle position and then you let the fadec take care of the sequence while you monitor the engine for no light off, hung start, hot start, starter fail to disangage - those conditions stem from my jet flying background and i am not sure they apply to the helicopter as well! - or you start the engine with the lever in shutoff and then you advance it into the flight detent at a certain percentage of gas generator?
During normal flight as the tl's are advanced into the flight detent, i presume just prior to takeoff, does the fadec or fcu maintain a constant rrpm's by mean of a governor and correlator as the collective is changed, varying the load on the mrs, if so which instrument do you refer to to set the power? Probably you then back it up with the engine temperature
Do you have an APR postion - auxiliary power reserve - providing an uptrim either manually or automatically in case of an engine failure on the remaining engine? And if so, do you select it manually?

Many thanks and my apologies for the lengthy post
