Maybe I'm missing the obvious here, but why don't we just make the
default value be:
/system/electrical/nominal = 1.0
/system/electrical/subnominal = 0.7
?
I agree that aircraft designers *should* take the time to set them to
real values, but we have to provide a default from C++ anyway, so
making it normalised rather than 12 or 5 or 28 seems easy. So long as
people understand that it's a default, nothing more.
BTW, I'm curious - what's the best way to create electrical system
components, especially voltage meters, generators and batteries, in
this scheme. My guess is they *should* use real volts, because if an
aircraft design is including them, then presumably they've configured
their system voltage correctly?
