Certainly odd that they're just catching fire while sitting on the ramp. 

Maybe it has something to do with being hooked up to ground power? Who knows...

Very strange that these events STILL plague the Dreamliner....I love this airplane,..it looks good and on paper it is good!...but if events like this continue to occur it will soon be nicknamed the screamliner!....heaven knows what would of happened if this electrical problem occurred at 35,000ft!

 

The electrical systems are very different on the 787 from other more conventional aircraft, the Dreamliner uses far more electricity, instead of  the usual pneumatics, to power airplane systems such as hydraulics, engine start and wing ice protection...it even has 17 small substations that provide load to local loads as needed!...all this electricity is generated by extra generators on each engine and stored in lightweight sophisticated lithium ion batteries.... earlier commercial airplane models, such as the 777, 747 and MD-11, used nickel cadmium (NiCd) batteries, which are heavier, larger and less powerful than the Lithium based ones.   

 

Oh...the 787 does NOT need any ground power to start its APU and systems, it is fully able to operate without electrical ground support so i doubt this issue has anything to do with ground support electrical power issues...

 

Also the 787 completed 5,000 hours of flight testing and an equal amount of test time on the ground. That testing demonstrated that the aircraft performed as designed....so why these electrical events are suddenly occurring is anyone's guess! .....I am sure they will be resolved..but at this late stage of the game its not doing Boeing any favours...Fingers crossed they soon overcome this and the 787 takes its rightful place as a remarkable and innovative aircraft.....Fingers crossed!
