Bell 412 start and performance questions
For the 412 drivers out there; a couple of questions please.
Why is it on the start procedure, at 12% N1 the throttle is opened past the idle detent all the way open then back to the idle detent, the idle solenoid activated then the throttle is set just below idle? Why not just go to idle, activate the idle detent then set just below idle? Does it have anything to do with the inner workings of the fuel control unit?
My second question is what is the best angle climb speed and where is it written? I have been quoted 45kts however no reference. This speed seemed a little slow to me, given best rate of climb is 70kts.
Thanks very much for your help.
Cheers,
