BA flies 747 on 3 engines LAX-UK - New EU comp rules

OK, tell ya what. We'll put you in the captain's chair of a 747 at 29,000
feet out over the middle of the Atlantic Ocean somewhere and make sure that
you run out of fuel. I'll bet you'll have a real warm fuzzy feeling then
knowing that your plane can glide for several minutes. -Dave


In the case of the Air Transat plane, one tank emptied itself fully
within 15 minutes, so they decided to cross feed from the other tank and
while doing so, didn't check the gauges and were then surprised to find
the other tank was now also empty within 15 minutes (the pumps were
essentially dumping the fuel overboard). The crew made many mistakes
including cross feeding, and not monitoring fuel once cross feed was opened.

In the case of this British Airways flight, fuel tank depletion would
have been at a steady continuous rate, and proper monitoring would
reveal how much further they can go before they are too low on fuel. If
they were 100% sure of making it to Ireland, 80% sure to Manchester and
60% sure to London, then they could proceed to Ireland over the atlantic
without issue, and there, re-evaluate fuel situation and decide if there
is enough to go to Manchester or London.

Furthermore, from LA to the Atlantic, the crew would have seen how the
plane performs and if anything else broke, and this would have given
them a good idea that the plane could go on for a few more hours. The
crossing of atalantic at northern latitude woudl have been much shorter
than going from lax to the shores of atlantic.

The atlantic is crossable on a route that doesn't bring you more than 60
minutes from an airport. Whether this flight used such a route or not i
don't know, but at northern latitudes, the distances to cross the pond
are even shorter.

Aircraft had sophisticated fuel gauges and computers that allow the crew
to know pretty accurately how much their have, and how much their are
consuming per minute at current rates. At regular intervals in the
flight, they calculate this and ensure that they have enough to make it
to 1- next airport, 2-destination.

Even with fully functionlaing engines, the crews have to regularly make
fuel checks during the flight and constantly recalculate their remaining
range, distance to next emergency airport etc.

Had they miscalculated while over the USA, they would have realised this
well before they ran out fo fuel and would have plenty left to get to
the next airport along the route.

If you dont like the answer, take the train.

How long does Amtrak take between Los Angeles and Hawaii ? Is the tunnel
glassed so yo can see the fishes and coral ? Is there a restaurant car
on board ? At night, do they have bright spotlights to illuminate the
seafloor so you can continue to admite the coral and fishes, or is it
very dark ?

people
i was into flying 15 years ago they had
747 before that they are geting old yes

I dont know, usually I'm asleep at that point besides, its too dark to see
out...

You don't think perhaps they have come up with some newer models since
then? It's like saying Mercedes Benz are old because I drove one that
was built 125 years ago.

The atlantic is crossable on a route that doesn't bring you more than
60 minutes from an airport.

Less, even.

Even when burning far more fuel than normal?

When you are burning more fuel, you need to find a shorter route, not a
longer one. But one that is guaranteed to be close to airports is more
likely to be long than short.
