Great job done by all concerned, I just hope that the lad's don't get blamed by the powers that be, although that could be hard having just read the interim report on the pilot website, PPrune.

Thanks for pointing out the PPrune site, some interesting stuff being discussed :)

I don’t think so, from what I can gather on the PPRuNE forum for some time they seem to have been of the opinion that it’s a fuel starvation issue, fuel waxing or icing, perhaps the electronic gadgetry that controls the fuel pumps/fuel flow. It’s still speculation at this stage tho

Re: Crash Landing

It is interesting to note that the spar fuel valve's on the 777 are not automaticly cut off when you pull the fire switch as they are on every other Boeing Jet Product.
To try and put this into laymans terms, it is similar to you turning off your ignition key on your car first, then disconecting the fuel pump.
In the event of an engine fire when you pull the fire switch you want everything connected to fuel and ignition to close and turn off. I see the FAA (American, Federal Aviation Authority) have set a deadline of 2010 to retro fit a auto turn off on fire switch pull, this time scale is normal.
The reason the crew did their actions simultaneously is simply down to time, in an event of evacutation being required.
Boeing's Standard Procedures are that both pilots will do their actions independantly, because when evacuating every second really does count.

So why did this plane ever get off the ground without auto cut off valves if the FAA insist on them?

Re: Crash Landing

Maybe thats a question for the authorities. The aircraft was certified as safe and the mere fact that there was no loss of life goes to show how safe flying is. I can only take it that Boeing had good reason to design the aircraft in the way that they did. This subject is being debated with some fever over on PPrune by Pilots, Engineers, Pax and others.
