Sorry to put it this way but the world will be a better place when the baby boomers are gone. f***ing stupidity is mind boggling.

Back on topic. So when I am at FL390 over the Pacific Ocean near the ETOPS180 point, and the battery has its event in its compartment, what is going to happen?

Nothing different than when it happens on the ground.
The battery is not used in flight except as a last resource back-up if you loose all electric power in flight, to supply a few seconds of essential electric power until the APU or RAT is started. And there is another battery that serves this same function too.

That is not to say that it's acceptable that individual cells or full batteries fail every one and then, except if "every one and then" is really very very rare.

It is important to note that:
- There was no fire in this event.
- Battery failures (and even fires) are not unheard off, even beyond the 787 and beyond the LiMH batteries (for example, the NiCd batteries also fail from time to time and even had a few fire events).

However, given the antecedents of the 787 and its batteries, and the small fleet and small number of flights hours accumulated by it, I say that this problem must be monitored very closely and I'm sure that Boeing is very nervous and putting a lot of resources to analyze this last event (despite keeping a "low profile").

This is quite the tidbit...

Old farts talk about the olden days when they would choose a heavier, lower capacity battery that didn't burn up laptop computers and planes were flown by pilots cranking wheels that pull cables that run down metallic wings and move flap surfaces- with no computer in the middle waiting to over rule the pilots at the wrong time because no one wrote computer code for this situation.

Now, bring on the young guy, telling them to f-this and f-that and f speculation that a battery that burned up before might burn up again, and tell them that it's all ok because he used his CAD design software and simulation models and modern engineering to make it safe.

The same, slick, fast-talking f-the-old-way shit that said that the o-rings on the space shuttle were ok and that "I've been pulling up the whole time"...

We will, and with good pensions and money in the bank. You will need someone on the seniority list to retire to enjoy it.

Just what the hell do you think this forum is for?

I respectfully avoid PPRUNE so you and your freinds who know what they are talking about can be free from such distractions.

And, I dunno, I think Bradley might be a bit overly dismissive when Per suggests that Lithium batteries seem to get really hot on occasion...and think that the Japanese culture of respecting old folks is at least part of the reason my Toyota is at 200,000 miles with the primary concerns being a worn out key and no place to plug in an I-Pod.

Nope, it was on a solid-fuel booster.

Concern: With cold temperatures the rubber may be too hard and not seal properly, allowing gas to burn through, potentially igniting the external fuel tank and leading to a catastrophic failure.

Decision: The cold, hard rubber does not present a significant risk.

Conclusion: Wrong.

Concern: After a fairly significant number of overheated battery events, over a relaively short amount of time, could one of these battery events (fire) cause significant damage or fire on board the aircraft and leading to a catastrophic failure.

Caveat: Even with a heat sheild, a recent battery event burnt the paint off the outside of the plane...

Decision: The batteries do not present a significant risk.

Conclusion: Pending...

I think he may be talking about Ethiopian's -unrelated, as I understand- ELT battery fire. Sorry if that's not the case.

Listen Boilerpuss, you're not the first generation to think they are smarter than the previous... Why is it I have to fix everything for all the younger people I know... Oh, they can all take care of their computers, but, a washing machine, a dryer, a refrigerator, water heater, furnace, automobile brakes, water pump, you name it, no one younger I know works on anything.... wtf are they all going to do when I die?
you still have to find a crew willing to fly this "barely airworthy" heap
no such thing as "barely airworthy" it's either Airworthy or Not
100% incorrect Ever hear of Ferry Permit? issued for Non airworthy aircraft

I fix everything that I have the means to fix: I change parts on my cars if it can be done in my garage, I re-wire my house, fix my appliances, and yes I build my own computers.

Question: without people hiring you to fix stuff, would you have an alternative income? You seem resentful for customers.

My comment about the baby boomer generation was overly generalizing and overly harsh but I do find that the older generation has a tragic tendency (and ability) to ignore inconvenient facts about the world.
