Every inch of it? No. I expect them to have processes in place to guarantee the specification of any roll of wire, and that to assure quality random testing is done at all stages of manufacture.
Phools...the record spot said:I wouldn't know. Do you want to tell me? And no, it wasn't about burn in. That's an add-in. At least, there are numerous examples of references to overpriced cables with no reference to burn-in whatsoever. So let's not try to shift the goalposts eh? But thanks, I'm glad to see you understand the rationale in why cables in the airline industry can't just be any old cable. Thanks.
Yes, Google's great eh? I look forward to numerous references from Ashley's other lapdogs in the near future all fully clued up on the above. I read the same thing too. Well, not that I understand it or anything...Overdose said:That's not Kapton though and the reason that Kapton is an issue (in some older aircraft), is that the insulation breaks down over time due to contact with moisture, this leads to cracking of the insulation at frequent intervals, allowing high temperature arcing outside of the insulation, aside from the shorting danger at this point, the high temperature of the arcing carbonises the insulation, therefore rendering it useless and actually turning it into a conductor.
It was Professor hat that suggested testing of such sensitive wire as fitted to some aircraft systems took hundreds of hours. It doesn't, it is as you say, monitored during manufacture and batch sample tested to ensure conformity to spec.John Duncan said:Every inch of it?

No, I read PH to say that aircraft require hundreds of hours as testing, but I'm a bit thick.Overdose said:It was Professor hat that suggested testing of such sensitive wire as fitted to some aircraft systems took hundreds of hours.

professorhat said:I don't think many people are concerned about the different nuances in the sound of an aeroplane or ultra sound machine though. So I'm guessing they probably don't bother with it.johngw said:Would anyone set their foot in an aeroplane that wasn't designed and tested through rigourous engineering principles? Did they really burn-in all those cables - if not, how can the auto-pilot possbly arrive exactly at destination having travelled 10 hours at 600 mph?
And did the hospital really burn-in the cables to that ultra-sound machine properly?
Not that I'm commenting on whether I believe burning in cables makes a difference to the sound or not, but I think you've not grasped what people are after when they do things like burning in cables.
If the hundreds of hours of testing refer to designing and testing of prototypes through to completion, then yes. If it means any aircraft coming off the production line after this period, then no, a handful of hours testing and checking would be all.John Duncan said:No, I read PH to say that aircraft require hundreds of hours as testing, but I'm a bit thick.Overdose said:It was Professor hat that suggested testing of such sensitive wire as fitted to some aircraft systems took hundreds of hours.

God, it's almost like spending £1300 every time a new pair of actives come out...
I already have. Oh, I forgot, ADM owners look down their noses at phools like me. Me with my AV receiver and Apple gear for source material too.Overdose said:Pot and kettle spring to mind.
How many components did you say you had lying around spare? You could have bought some decent kit with that.![]()

Andrew, I am sure that you are to young to have seen Sir Thomas's appearance in 73 but I would have thought you would have remembered his appearance a decade later.Andrew Everard said:Which would have been remarkable in itself, given that he died in 1961.davedotco said:I could have swore he said audiophile, after all he was speaking at the Heathrow Hi-fi show in 1973.

If you want an é hold your finger down on the e button for a few seconds and it brings up options. Do the same on the .com button and it brings up a .co.uk short cutdavedotco said:Touche.

Though you have to admit that some of the idiocy on this threat is of a truly great standard.
Strangely the only thing of interest that I can remember about the cables in Boeing aircraft is that they were, at one time, installed by ferrets.

I believe that Stainer suffered a very similar fate to that of the recently deceased actor James Gandolfini: neither could be described as having died at their own hand.davedotco said:His description of the fate that befell the composer Stainer, at his own hands no less, stays with me to this day.
Sadly he lived long enough to write "The Crucifixion" which I had to sing in several times (before my voice broke) and which is surely one of the most tedious pieces of music ever written.Andrew Everard said:I believe that Stainer suffered a very similar fate to that of the recently deceased actor James Gandolfini: neither could be described as having died at their own hand.davedotco said:His description of the fate that befell the composer Stainer, at his own hands no less, stays with me to this day.
