Oh dear, looks like Boeing is up sh*t creek without a paddle. The gamble on more-electric technology isn't paying off, Elon Musk is criticizing their battery design, and even the employee who was fired for rejecting the battery during testing has come out of the woodwork. Sounds like they need a dual-source solution and fast!
Hrm... on most passenger flights, probably 3 quarters of the occupants are probably carrying some sort of mobile device powered by a lithium ion battery. This seems a little over-zealous and under-informed to me.
This sort of thing is supposed to be caught in qual-testing. Apparently they only took an ideal duty cycle into account, but this is a MORE-electric aircraft, so those batteries must take a pounding.
If aircraft systems are migrating to more electric, but the electrical systems aren't being designed to take a harsher duty cycle into account, then more-electric = more-dangerous.
There are better ways of making aircraft lighter and more efficient than just turning them into a flying power sub-station, but electricity is the future, and anything not powered by the blue smoke is old-fashioned right? Well this is the result... but I'm sure they'll overcome the teething problems, except when these airplanes get old every A&P mechanic is going to need a degree in electrical engineering. Blah blah ok rant over...
I flew out of Heathrow on Saturday, no problems for me, but I was flying United. Maybe BAA needs to take some advice from Jeremy clarkson and convert combine harvesters into snow ploughs? It's a bit embarrasing when a flurry of snow reduces a so-called world class airline and the world's busiest airport to shambles!
