EC135 P2+ starter limitations
The flight manual states: "When starting engines, the starter energize time is the time which elapses between initiation of the starter and ignition in the turbine."
What is ignition in the turbine suppose to be?
We have 40Ah battery installed so the FM limitation is 15 seconds starter energize time. Our EC takes 25 seconds from switching on ENG switch until it reaches 50% N1, when the starter switches to generator mode.
