Default Is the 787 a failure ?

These URLs may be of interest. If an emergency is defined as an
event that was unanticipated in occupance and limited in duration,
clearly this is no emergency.

That's TECHNICAL ... "legal" ... has NOTHING to do with how
potential passengers should act or react.

Passengers are convinced the 787 is a death-trap. That's ALL it
takes to destroy it.

You are convinced passengers are convinced. There have been no deaths,
no injuries, and only limitted damage to this point. A minor tweek
will likely solve the battery problem. It appears to be a problem with
the APU not knowing how to handle Lithium batteries, as the problem
occurs when on the ground with the APU running the system.

I love it when people who have no ****ing idea what's going on, make
**** up like "a minor tweek will fix it".

When you look at the complexity of the APU unit, it WILL be a
relatively minor tweek.


Right. The APU is complex, ergo the solution will be simple.

Or maybe you're trying to say, the APU is simple, so the solution will be
simple.

Either way, you're ignoring the complexity of the entire electrical
system. Which kinda makes you claims absurd meaningless and laughable
prattle.

You sound good, tho'. Keep pontificating! Maybe you'll fool someone into
thinking you know something.

So, how many days has it been? Where is that simple tweek!?

LOL!

Just because the tweek will be minor does not mean figuring it out
will be simple. And getting it signed off will not be a simple matter
either - we ARE dealing with certified aircraft.
I suspect there will be some reprogramming of the charging system and
a possible switch to Lithium Iron Phosphate (LiPo ) cells from the LCo
(Lithium Cobalt Oxide) batteries that caused a lot of consternation in
portable devices, like laptops, a few years ago. I cannot understand
why LCo batteries were spec'ed instead of LIPo or LNMC cells. The
relatively minor power density advantage is hard to balance against
the known issues with LCO cells. The LCO cells CAN be safely used
with proper controls - but the risk is still there.
