New design. Big changes. New issues.

Hi,

Walnut:

Quote:

Boeing decided electric cables were lighter? & simpler to transfer high load items. However unlike hydraulics which tend to leak in failure mode, electric cables if overloaded tend to catch fire.

One of the most studied, discussed, quantified, checked is the Design Philosophy and the concepts adopted. Boeing decision for the change to this innovative design involved even the engines (bleed issue) and the mentioned 1.45 MW shows the "magnitude of the electrification".

Would be fascinating to discuss in a Thread the comparison of hydraulics/pneumatic vs electric. I´m mulling the idea. After the crisis recedes.
