Asked by: 1877 views Helicopter

A snag recently encountered. While trying to run, one PS was at 71% N2, then while rolling up the second pwer Section to 100%, the second one would drop off to 61%. Didn't matter which side transferred to both PS. Thanks.

    Mr. Sabastian and Mr. William, this is not a problem in Bell-412. this is because of it Governor settings. its is with all Bell-412 that when you open 1 engine throttle above 61%, the N1 of other engine drops.
