While comparing the Flight Manual to the numerous other bits of paper claiming to be checklists, I found an interesting bit which the engineers couldn't resolve:
After starting Engine 1, the RFM says to increase N2 to 77-85% before starting Eng 2.
BUT! It says that if Eng 2 is started first, the N2 MUST be 85% before engine 1 start.
Why the difference? The engineers say that a lower RPM, around 80%, for engagement is preferable to stay away from the band of vibrations.
Nick Lappos, you might be in the ideal position to answer this one?
