Confusion exists because early POH and the factory course said to go to pre take off power prior to doing checks the latest manual says to go to flight idle 63 to 65 ng to do them ; then run it up; much more pleasant 1 min cool down all similar to as350
Pilots should check rigging on the throttle; flight idle should be 25% on the card on the engine
Also the trap I fell in to today rotor rpm can only be checked, in flight itself , if the engineer runs it up to say 405 on the ground it will be 420+ in the air and close to max +
If second start and its over 150 don't set it at the white line; start at off position run up to 10% and the go up just like BA as350
