A hypothetical situation, and a doubt

Hmmm... lost two of eight huh? Eight engines, you a Buff driver?

Yep, that dreaded 6 engine approach...

I know it isn't what you're saying but if you lose one engine in a
4-engine craft, you don't return but carry on, surely?!


No, that would probably be a bad call. You have just suffered an accident,
you don't really know what other damage there may be, to other engines or
otherwise to the airframe, you are already at your departure airport, where
at least you assume you can land safely, so knowingly launching on a flight
(which may be a long flight, if it's a 747) with reduced margins would likely
not win you much airmanship praise. Your biggest problem though, in this
case, is that you may be too heavy to land safely - If it's a question of
climbing to where you can dump fuel, and/or flying around to burn fuel, and
your main airport, with the best maintenance facilities is a couple hours
away and you're confident, from the nature of the accident and the engine
monitoring instruments that you're not about to lose two more, then your
passengers who thought they were headed to Singapore may end up in Atlanta.

It was BA which returned to Bangkok after losing
no 3 engine on takeoff in a 747-400. The roll
felt to last forever and we lifted shortly before
opposing PAPI lights. We climbed to Gulf of Siam,
dumped fuel for nearly an hour and returned.


This happened about ten years ago.

Maybe that is what happened he http://www.cnn.com/2006/US/04/03/c5.crash/


I believe he (C5) lost 3 of 4, not just 1 of 2.
Of course I have lost 1 of 4, and even 2 of 8, and returned safely. Granted, we could not dump fuel with the 8 engine
bird, and had to fly about 5 hours to burn down to landing weight.

From what I read he (C5) lost #2 only....

I give them thumbs up for their decision to continue that flight, from
California to England, on 3 engines.

Safe does not = risk free.

Regulations require that any failure requires a landing as
soon as reasonably possible. If over the open ocean with no
place close, you still divert and land at the nearest
suitable airport. This may be your departure point, the
destination or some airport along the way.

It was BA which took a 747 all the way from LAX to the UK on 3 after a
loss on takeoff just a few months ago.

In a smaller plane (light twin) the available power is not adequate to
perform a go-around on one engine with adequate safety margins, and you
must get it down, even if you break it. In a transport plane with two
engines, it is perfectly possible, but you must weigh the risk to benefit
ratio, and maximize crew resource management to make sure everything is
done by the book. In a 747 you should hardly notice any performance loss.

Scuse me.. I'm not a multi driver... let alone a 747 pilot...

but if I lost 25 percent of my power I think that I would notice some
performance loss...
