In case you're responding to something I wrote rather than
to Floyd (it's hard to tell, what with all the quoted text
you included)...
Actually, they use bleed air generated by the APU, which in
turn is started with the battery. (The APUs on the newer
models generate electricity also, but the engines still use
pneumatic starters.)
But I didn't mention C-130s in connection with batteries. I
mentioned them in connection with somebody's assertion that
the ones flown to Antarctica are never shut down, but are
flown out again after unloading/reloading because of the cold.
Where I mentioned batteries was in regard to the small recips
or turboprops that Floyd was describing before he mentioned
737s.

IF the APU requires a battery for start, it doesn't take
a whole lot of energy to do it. |
Actually, it uses a pull cord like a lawnmower. If you've
ever noticed bootprints on the left landing gear sponson,
that's why.

F-15s don't even have a battery. |
How can an airplane not have a battery? What provides
standby power to things like instrument inverters and
lights in the event of an electrical failure?
