Jcooper thanks , I was missing the 80% thing...
Grainger: We need to turn off the governor to do magnetos checks etc. (but it isn't shown on the checklist) so there is another time the "governor on"?
Anyway in our checklists we have a "throttle closed" before starting the engine, I can't see the need for a "governor on"
I'm also wondering why my school is teaching to do the checks at 100% when in this checklist shows at 75%? (no matter?)
And why in this checklist you must do the low rrpm check with GOV ON, aren't you forcing the governor without need?
He**! I will have a talk with my school, I would like to have access to all those amendmets, new checklist etc.
Thanks charlie s charlie for posting
