Dangit, that is just the thing...
Thanks sfo
My very first a/c was a 1966 J model Cessna 182. I obviously am weak in the technoELEC.
Having noticed an architecture in the 787 that mimics fifty (sixty?) year old technology, as to back up systems, how behind the times are regs, and FAA?
For all the flak Boeing are taking, it must be grating to put a battery in their electric jet.
Aside. LiH is what makes the Hydrogen bomb go boom, no?
For my money, a sufficient amount of compressed air and a small turbine would be safer and more dependable than Lithium, imo. At least to start the APU.
thanks, Bernd
