I’m confused in this accident why the Eurocopter EC135 pilot decided to manipulate the throttle after encountering wake turbulence - I can’t think of a reason for this. Could someone please explain why a pilot would do that?
It's the second sentence on the first page of the report:
He inadvertently rolled the throttles to manual, and never restabilized the engines or main rotor rpm.
Supplemented by (the next sentence):
In addition, he did not understand the reset procedures for the engine controls (FADEC), and never returned the engines to FADEC control.
