GE CF6 Question
As many of you know once in a while a question comes up that seems self-evident but is not covered in the “book”. We operate the B-747 equipped with the GE CF6-50E2 and place the start lever to idle at 15% N2. Is there any problem associated with placing the start lever to idle late, i.e. 18% or 20% or max motor? The best example that comes to mind is during a start abort after motoring to lower EGT for a new start attempt.
