With Mr. G Dot's post, we've now come nearly full circle in the thread.

The PM's antenna farm radiations coupled with a nattering nymph's Nintendo DS
in row 13 caused both metal-encased & shielded ECC units to go bananas.

Ice was a related factor as there was not...

Perhaps, but we've gone from BC to AD and have come up with some new myrrhs for the lamp oils since then. :p

Seriously Rev, I think the Trent might be the canary in the coal mine and there are...

GE matters aside, it is interesting that both roll back aircraft (Delta and British Airways) were uplifted in China.

During the NTSB testing, they discovered that ice is stickier and more...

You are correct of course AFM. :ok:

Then there are the people in a quiet room somewhere at Mega-Corp Airlines' home office that crunch such numbers regularly. Our regulators also play this game,...

DeScally of BC:

As long as procedures are in place to prevent at least the EDIT: one in 100,000 /EDIT chance of a repeat occurrence, I doubt a grounding order will be issued.

AFM

Interesting. So you're saying the combined cross-sectional area of the FOHE's is actually smaller than a metering valve or nozzle? Or are you referring to only one of many tubes within the...

Boeing hasn't said exactly that. It is the combination of the Trent engine and the airframe fuel system that will require tweaking. Engineering on both sides obviously missed some low-temperature...
