Re: Atlas Air Purchases Four Boeing 747-8 Freighters

Given that 3D-printing is becoming more and more important, would it be possible to make the parts where tooling has now been scrapped that way, using composites for example (still likely requiring re-certification)?

Re: 787 System Question

IIRC, the flaps and L/E devices are driven by the center hydraulic system. That system has two ACMPs (alternating current motor pumps) that operate on demand. The L & R systems have an EDP and elec pump to supplement the EDPs during high demand operations. The hydraulic system operates at 5000p...

Re: Should Airbus bring back a modernized A310?

You might love it, but airlines don't. Wide bodies always have a higher fuel burn than narrow bodies, so if possible they always prefer narrow bodies.

Re: Should Airbus bring back a modernized A310?

Length roughly: A310 47 m, A 300 54 m, A330-300 59 m I assume Airbus would have preferred an A330-200 and a shrink if a good, weaker engine had to be available. A shrink to A310 length is probably overdoing it. So yes, a 170-190 t MTOW plane with A330 fuselage, 51 m carbon wing and new engines is a...
