Technical Details of Airbus Wiring Problems

From: "andrew cooke" <andrew@...>

Date: Sun, 21 Jan 2007 20:47:20 -0300 (CLST)

Airbus just announced that they had solved the Airbus wiring problems -
http://news.bbc.co.uk/2/hi/business/6284449.stm

But what were the problems?  They seem to have been both technical and
cultural.  On the technical side, it seems that different teams (in
different countries) were using different versions of the design hardware

On the cultural side, it seems that the German designers screwed up,
largely through inexperience -

This quote from the final link above: "With all the problems associated
with the design and production of the A380, would you be willing to fly on
this airplane along with over 500 other passengers? Can you imagine the
problems with boarding and leaving the aircraft, and retrieving luggage?
And will there be enough restrooms? Also, I'm not convinced that aluminum
wiring is safe  it was used in some California homes several years ago
but was discontinued because of power-related problems."

It turns out the aluminium wire tends to make poor mechanical connections
