What a load of crap, so fly the 787 180 Etops, it catches on fire and then its ok..
How
exactly would the aircraft catch on fire?
No the 787 should be Non ETOPS till they find the cause, if they cant then good bye to Li Ion baterries and redesign with proven Nicads and recertify the electrical system..
There was no common cause to the two battery incidents. They made improvements to every aspect: fabrication, charging & discharging, wiring, monitoring, and containment.
Suggesting NiCads is foolish and reveals a lack of understanding of the system.
You cant let an aircraft fly ETOPS if it has a fault and you cant find the cause, thats just tombstone statistics to even try!
All potential causes are addressed in the updated system. Of course it should fly ETOPS - the 787 has twice the electrical redundancies of a 767: four engine generators vs two, two APU generators vs 1.
