Testing the A380 on CH4
Those French test pilots are totally off their trollies 
You have got to have massive ***** of steel to do their job. 
The issue of the wheels not coming down smoothly and the test team just accepted as OK, err hello you undercarriage doesn't open properly and thats fine?
Very good programme with such a detailed insight into geretting a new plane into the air

I saw a different program on test pilots a while ago. They are all totally barmy. They have to trust engineers (nowadays including computer programmers ) have got it right when they fly a plane for the first few times. Even after that it's still pretty hairy. They are certainly made of the right stuff.
BTW, is "geretting" some aviation term I'm unfamiliar with?

It was an interesting programme, I really enjoyed it.
The bit about the wheels was only during emergency lowering if the main system had failed, the wheels are usually blown down with high pressure nitrogen in the jacks assuming that the hydraulics have failed. The normal sequencing does not work so the wheels drop before the main doors have fully opened and that is why they hit the doors. The teflon paint allowed the tyres to slide past the innner skin of the doors more easily. They were happy that it appeared to work anyway!
The tailplane of the aircraft is almost the size of the Vulcan's wing! That set it into proportion for me.

What an amazing plane.
I make aircraft parts for a living so found this programme fascinating. We have m ade a few bits for testing but no actuall parts for the plane.
It was amazing to see the plane take shape and how all the parts got there.
But teflon paint did anybody else think that was a bit of a bodge????

Yep I thought the answer would have been to make sure the bay doors were open further apart, not just stick a bit of teflon paint on and say oh yeah that works a treat. If thats their answer to a problem it makes you wonder what other engineering marvels they came up with to fix 'problems'.

the teflon paint thing will be only a short term thing, even when the aircraft moves into service they will be looking for a more long term fix? most aircraft have problems which get fixed during maint checks whilst in service.

I was a trifled worried when they were introducing the wing into position against the fusilage.
It was then noticed that two bolts hadn't been removed.......how does it go? For a ha'peth of tar the ship was lost............To me, that was a glaring oversight.
Flipping amazing plane tho'. Wonder if I'll ever get to ride on it?

Its a lot better than landing on them though Brother Will. I once aquaplaned 8500 feet on a runway after a thunderstorm and was not told about the standing water! That concentrates the mind a bit.

There was a series about the Beoing 777 some time ago which was interesting. It showed how various depts design their own bits on CAD and then an overnight program joins them all together and spots where components overlap and need re-designing to fit properly.
Missed half of the one last night, damn, but facinated by the guys and their toilet system. They were really proud of it. Hate to think how much it costs if the final version is made out of titanium tubing.
