RE: 7E7 Radical Changes

Dl757md- Starter/Generators are DC not <acronym title="Air Canada">AC</acronym>, as the big generators are going to be. More then likely these engines will have a completely separate starter. That's not even starting on the subject of the historical reliability of starter/generators on the smaller t...

RE: Prop Speed Question

Efficiency and power production are also two different things. All propeller aircraft with variable pitch props t/o at lowest pitch-highest rpm. However at high speeds, higher altitudes etc. its more efficient to operate the prop and engine at a larger pitch lower speed. <acronym title="Solomon Airl...

RE: Recirculating Lavatory = Blue Water?

Horizon's CRJ700's come straight from the factory with recirculating blue juice lavs. Same with brand new Q400's. Whether or not there's a colorless "blue" juice out there or not I couldn't say. But because it recirculates I wouldn't imagine it would take long for it to reach a pretty disgusting col...

And it means absolutely nothing to their jobs, so why would he be bothering with it. And why was this mecha...

RE: Final Assembly For 7E7: 3 Days

I'll believe 3 days when it happens. I guess the real question is what is Boeing's definition of final assembly, if they mean, structural components ok. But if they mean, engines, gears, flight controls, interiors, painting, rigging, et cetera then I don't buy it.
