A 380 (Merged)
In a recent cockpit layout picture of the A 380 I have noticed few new things.
For instance two instead of three hydraulic systems.
Is this another way to loose some weight or simply a following trend? Boeing 787 is without bleed air system completely relying on electric even for pressurization. V.S.S. (very simple and smart) but it could be "Very Simply Stupid if you loose your hydraulic redundancy. Concorde started with Green.Yellow and Blue many years ago.
Any comment guys?
