CCQ with the dash 8 presents many problems on many levels, evidently many operators around the world have tried it and subsequently dismissed it based on %#^% ups. The two different types (yes I use that term) are completely different animals. I understand commercial pressures, but from a flight ops point of view....I see trouble, pity the poor Mildura lab rats as mentioned in the "letter to pilots" that endure this proven failure that will possibily result in their personal records tarnished to feed corporate bonuses. Something has to give.
