787 Number 2 landing

Minor hiccup the way I see it. Boeing is putting plenty of flight testing time in since the first flight took place including 5+ hours today.

Overheated brakes aren't uncommon during flight test. Here's what happened to the A340-600 during its rejected take-off test. (The action starts after about the 3:40 mark)

I'm surprised Airbus released the footage. One can only imagine them telling the tower 'uhh, we're gonna need the runway for a while'



By comparison the 777 RTO test. (Far less dramatic)

And, for fun, a test of the A380 brakes (outside the aircraft) for an overweight landing -- also pretty spectacular

Also interesting, the A380 program had gear door troubles during the flutter test - leading to a redesign of the panels

 

Didnt know which 787 thread to dump these in, but some cool comparisons related to the 787.

That first video is cool. It's amazing how much the wings and how fast the wings lose their lift as soon as the spoilers are deployed. Don't get to see that from this viewpoint very often.

 

Yesterday looks like another milestone in flight testing program as in the 5 hour flight the reached and altitude of 30,000'

I cannot wait till they get one out to Glasgow, MT for noise tests and I can shoot some photos of this beauty in action.

 

What is happening with altitude at the 3:42 mark?

 

Looks like ZA002 is returning to Everett after "cheese cloth" was found in the fuel tanks and filters.

I'M NOT AN EXPERT.

If I am reading this right it looks like an emergency decent exercise similar to what they would do in the event of sudden cabin pressure loss/ oxy mask deployment etc...............

 

Thought about something like that for the sudden drop, but I wasn't sure if even a 23,000ft drop in 1 minute was reasonable or possible. And on the next line, is an 18000ft per minute climb possible?

 

As above, I don't happen to know the details of this flight, but there is a possibility that they were running a 'flutter' test, which is basically a high-speed dive designed to prove that the airframe can reach/approach its theoretical maximum speed and remain intact.


In the A380, flutter testing about ripped the gear doors off, leading to a redesign of the gear doors & several underbody panels

So far the testing has 60 hours completed.
