Crash threat

A Qantas 747 with 344 passengers on board could have faced
catastrophe after losing power from all four of its generators on
its descent into Bangkok on Monday.
...
The Australian Transport Safety Bureau said it had been told the
power from the main generators was lost 15 minutes away from
Bangkok.

...
"In this case it looks as if it has gone to the last stage of
emergency power for communication and navigation," Dr. Arvind
Sinha, director of aerospace at RMIT University in Melbourne, told
the Sydney Morning Herald. "After that it comes down to the skill
and experience of the crew." He added that the loss of all four
generators is "unheard of" but Murphy can and does find a way,
this time through a sink with a clogged drain in the first class
galley. ...

The sink is right over the electrical distribution unit and Boeing
engineers evidently considered the potential for leaks when they
put it there. A drip tray is installed to catch any overflow from
the sink but the tray on this aircraft was cracked.

Did you really need to post it twice? And we know it wasn't an accident
because you've got 2 different pre-post comments.


Now for the guys with "Heavy" experience. Does the 747 really only have
enough onboard battery power to last a little over an hour for the
flight deck?

Yes, that's about all the time the batteries will last.

About an hour depending on the model, BUT, they can just start the APU
and this would run at least one of the main busses.

Does the apu power go through the same distribution panel connected with
the problem?

The vast majority of news servers stopped honoring cancel messages
yonks ago due to abuse.

You really ought to know that there isn't a mainstream news server on
the planet that still accepts cancel commands.

You ought to know that AT&T Worldnet honors cancel commands. Given
that they were the backbone for arpanet/usenet in the '80s, I'd
characterize them as mainstream.

You have a cite for that? Because if it is true I can set up a script
that will do a lot of good for the rec.aviation community.
