I avoid thinking of all of the things that can go wrong, and thank my lucky stars when we make it.

Well said.

A very detailed and interesting article about the Dreamliners lithium ion batter system.

Thanks

1323049 2013-01-19 04:23:00 What do you think Airbus is made of?

Carbon-fibre reinforced plastic, glass-fibre reinforced plastic and quartz-fibre reinforced plastic are used extensively in wings, fuselage sections (such as the undercarriage and rear end of fuselage), tail surfaces, and doors.

And...

Major structural sections of the A380 are built in France, Germany, Spain, and the United Kingdom. D

Interestingly enough,


And Boeing isn't the only aircraft manufacturer that should be concerned—Airbus also uses lithium-ion batteries for its newest APUs.

The old radial engines coughing and spluttering. None of these computers flying the plane like the Airbus and Boeings.

1323051 2013-01-19 08:39:00 Bring back the DC-3! No Li batteries in those things!!

Just read that article, I don't like the sound of those batteries, I thought they had a cooling system, poor design by the manufacturer and Boeing for not installing/identifying the risk. I haven't read much on the dreamliners operation however I really don't like the sound of their electrical system as a whole. Having a primarily electronic system is just bad news. As demonstrated in the US incident, a substantial loss of power is pretty bad, had a larger disaster caused more damage or the RAM turbine been infective there could have been a much worse situation on hand. Having an option for a majority of flight surfaces to be controlled manually is very desirable, I'd hate to think what would happen should all electrical power go one one those. Sounds like extremely minimal control would be available.

I'm not too sure if the move away from bleed air systems is good, to me it's a good system because as long as the engines are operational the cabin can remain pressurised, the APU can be started and stopped/engines started and stopped with the APU in flight, anti icing systems are also online. What happens if that power failure occurs during icy conditions? I doubt that RAM can provide enough power to de ice the wings, they hardly provide enough juice to run the ICAS!

1323052 2013-01-19 09:17:00 Quite right. Bung in all those safety systems and just in case, duplicate them. Safety will be hugely enhanced, if only because the extra fuel required will remove the possibility of carrying freight or passengers. They could also add more RAM to remember about bountiful energy reserves ;) R2x1 (4628)

How do you control the surfaces manually ?
I thought the very first Airbus's were "Fly by Wire"
And they've sold several thousand of them.
