Did they ever find the cause of the accident?

serious design flaw in all of boeings recent planes? You know, the control computers all running the same softwrae made by the same manufacturer

oh that and hiring the same mexicans that Zoom used to employ to fill it with fuel

Last thing I read was that they were investigating the theory (probably discredited by now) that the extreme cold on the flight from China had altered the fuel density and the pumps simply couldn't get go-juice to the engines fast enough.

Last I heard they said the fuel was fine, no bird strike or such, but there was some talk of fuel pressure not being correct. Can't remember where I heard it, but it made me wonder of they've found the problem/solution.

I've got quite a few flights booked on 777s so I'm curios to know if they've nailed it yet!

didn't they say that for some reason the fuel lines were showing a temperature that was 20 degrees lower than they should have been because of some rather bad weather over Siberia?

I think it is, certainly a few weeks ago you could see it over by the BA service place

I thought that it had been broken and sold for spares on Ebay. Didn't BBA bid on the computers to run T5 baggage handling biggrin

The latest info is that both engines weren't receiving enuogh fuel, and there are signs of cavitation having recently taken place on nozzles in the fuel pumps. The fuel was found to have considerably exceeded specification, with comprehensive tests having been performed on it. RR are using a modified test cell to try and replicate the conditions.

I had a couple of hours in one of the BA 777 simulators at Cranebank last weekend, courtesy of a mate who is a training captain on type.

We didn't have the Blue Screen of Death on any of the cockpit displays, but it did sulk for five minutes after one landing, convinced it was still flying. It was probably still in shock after my first attempt, when I thought I'd knocked it off the hydraulic jacks and onto the floor.

Mate: "When the radalt calls thirty, gently raise the pitch - its not really a flare"

Me: "Right Oh"....

Radalt: "Fifty...Thirty"

Me: "Strewth, its quite heav.."

Simulator: B-BANG!

Me: "F...."

Mate: "...there's the mains and...."

Simulator: BANG!

Mate: "...thats the nose gear"

The yoke forces are very heavy if you don't have it trimmed correctly, and the trimmer stops operating once you get past a certain angle of attack, and its a decent effort to keep pulling until the stick shaker starts and the thing starts buffeting - the FO in the Hatton Cross glider was dragging the thing in towards the end, and must have used a good deal of brute force in the process.

And no, my mate doesn't have a view on what happened either.

Tried a full Cat3 no-decision-height autoland into pea-soup - very spooky just seeing the runway lights emerge out of the gloom at the last second, and a 40kt crosswind autoland just to see what it did - amazing bit of kit.

I did notice at the end that one of the simulator control touch screen displays disappeared to be replaced what looked suspiciously like an old X11 display with a shell window running a bash shell - so the irony is it was a bit of Unix gear.
