I stand corrected.
I wrote my post out of my apparently not so good memory. Checklists were made for people like me.
According to FCL 2.001 and the Icelandic regulations on flight crew licensing (based on JAR-FCL 2 Amd. 6), this is exactly as you state, i.e. Rotors turning time.
"Flight time:
The total time from the moment a helicopter’s rotor blades start turning until the moment the helicopter finally comes to rest at the end of the flight, and the rotor blades are stopped."
So how does one log the rotors turning time if the helicopter is wheeled and you only do some taxying during maintenance and such? Or when only doing ground runs? No flight in there is it?
Sorry for the confusion people.
