Jet Flies On With One Engine Out on Nonstop Trip to London

But he landed only 167 miles short of his destination and presumably had the
required reserves at that time.

Presumably.

A great circle route between LA and London
crosses Greenland, passes near Iceland and then overflies Scottland and the
UK. I don't think that you can make the case that there was a big risk of
running out of fuel far from an airport. In fact, he could have landed in
Scottland with about 40 minutes more fuel than he landed with.

Perhaps. I presume there runways adequate for B-747 operation in
Scotland and all those intermediate airports.

It will be interesting to see what the whole story is.

I doubt the "whole story" will ever be completely revealed.

It probably comes down to deciding to continue after passing each suitable
airport with plenty of fuel to reach the next suitable airport. The airports
are only 500-700nm apart so he was always less than an hour from a suitable
airport.

Thanks for that information.

I would also doubt that he made this decision without consulting his company
dispatch.

Right. But given the BA policy, I'm not sure their input was safety
oriented.

I guess that I might feel differently if the flight was going from LAX to
Sidney and decided not to return or to land at Hawaii.

Definitely.

It seems kind of wierd to me too but then most of the pilots that will weigh
in on this topic continue on one piston engine one every flight and this guy
had three jet engines!!!

That brings up another issue. What would you estimate the flight
characteristics of a B-747 to be if the other engine on the wing with
the dead engine had failed? I would guess it would be virtually
uncontrollable without reducing power significantly resulting in a
forced descent.

And another issue is, if the engine failure had been a result of fuel
contamination, how did the PIC determine that the remaining fuel was
safe for continued transcontinental flight?

Additionally, when the engine failed, ATC mentioned sparks being seen.
How did the PIC determine there was no structural damage to the
airframe as a result of the engine failure?

I would fly either BA or another airline based on schedule and fare. Are
you safer flying four engine BA airplane or on an somebody else's two engine
airplane?

I don't have the requisite experience in airliner operation to begin
to answer that question.

Certainly in Scottland since two collided on a runway there. Sondre
Stromfjord in Greenland is long enough (I've seen 747s there) and so is
Keflavik in Iceland (I've seen 747s there too).

I would suspect that the press will drum up enough concern that there will
be an investigation and the story will come out.

Right. But given the BA policy, I'm not sure their input was safety

I was not aware that BA had a bad safety record or that the passengers were
exposed to much risk.

I think that four engine airliners have to be able to fly with two engines
inoperative on one side but I am not certain. They can probably fly on one
outboard engine at certain weights.


And another issue is, if the engine failure had been a result of fuel
contamination, how did the PIC determine that the remaining fuel was
safe for continued transcontinental flight?


That seems remote. Has it ever happened? Could it even happen? Jet
engines can burn almost anything that is flamable. Seems unlikely that you
could even find enough of anything, except Jet fuel, at LAX to fill a 747!
Maybe they know why the engine failed.

Additionally, when the engine failed, ATC mentioned sparks being seen.

airframe as a result of the engine failure?

I think airliners are required to have burst protection built into the
nacelles to contain failed engine debris. I know that the 777 has this (saw
it on TV!)

I don't either, I just think cheaper is better.

I have found over the years that when a group of smart people come to a
decision that seems crazy to me, it only seems crazy because I didn't have
all the facts that they had. Based on this, I give people the benefit of
the doubt.

Are you thinking of Tenerife? That's in the Canary Islands, not Scotland.

I was, my error. The runways at Glasgow and Edinburgh are long enough and
I'm certain that they are in Scottland.

It's unfortunately too easy to mix in the memory the pictures of a
devastated Pan Am B747 lying around after the Tenerife accident and pictures
of a devastated Pan Am B747 lying around after the Lockerbie bombing, which
was definitely in Scotland.

Er, when?

(But you're certainly correct in that Edinburgh, Glasgow and Prestwick are
probably all suitable for landing a B747.)

This is the reason why they have rudders so large that they can be
ripped off when unproperly used.

New certification requirements want them to be able to take-off with two out
on the same side at max gross. The A380 for example will have to be able to
do that. The 747 needs three for take-off.

That will never happen. Now..you might mean "continue the takeoff
after V1", but the aircraft cannot accelerate to V1 at maximum
weight and remain on the runway with only two engines on the same
side operating. In fact, the 747 cannot do it on three engines at
maximum weight. It can however continue the takeoff after V1 if one
engine fails at maximum weight.
