Li Ion batteries are "aviation friendly"?
Hi,
"Fault Tolerance and Graceful Degradation" are essential characteristics of good Systems.
An aircraft to perform this must rely on adequate parts.
I question the use of Li Ion batteries as MAIN and APU with the current "aviation industry conditions". (including Certification)
IMHO we still lack SEVERAL IMPORTANT pre-requisites to use these batteries for above mentioned applications in airliners.
The pre-requisites cover ALL issues capable to generate (BIG) problems ranging from technical to organizational aspects.
If EADS is questioning and considering alternate solutions for A350 i think they are correct.
We engineers like "hi performance" parts in our design.
But, we must question everything prior to mass producing.
