he 747 is noisy (much much noisier than the A340), the plastics rattle, the design of the interiors is outdated
Yes I must admit I had to stifle a giggle at that comment. Whilst I'll grant you our 744s are noisy and tatty [due to lack of investment] compared to the Dugong my understanding is that the lack of ambient noise on the A380 brings it's own set of unique problems.
As for rattling interior fittings well that is most definitely not a problem the 744s have ever had. On the other hand the product from Europe that I do operate on [A330] rattles alarmingly on take off and landing. I doubt the A380 is any different.
Is it
all the seats in A zone that move due to foot traffic/floor flex or just 1K?
What about the "Russell Crowe memorial stairs" at the front of the aircraft that groan so loudly [lack of ambient noise] that no one can use them during the night ?
The same for the cart elevator............?
