David,
Just had a look at the latest additions, good work, this is an area
that has been very lacking in flightgear and it's nice to finally be
addressing it.
The airspeed indicator is still working for me, even when the static
system not servicable.

Your code should be able to simply check the property:
"/systems/electrical/outputs/turn-coordinator"
We aren't yet modeling a degraded/degrading electrical system so as

If you want to parameterize your turn-coordinator modeling code, In
the C172S (serial #'s 172S8704 and on) the turn-coordinator is fed
from the "electrical bus 2" aka:
"/systems/electrical/outputs/bus[1]"
But it will likely be someplace else in other aircraft ... even
earlier serial numbers of the C172S (which I was referencing) feed the
TC from bus #1.
Why can't there be a universal standard for how electrical systems are
constructed in aircraft?!? I know! I'll come up with a standard
myself ...

Yes, if someone could come up with a simple model of a battery, and
alternator we could add those pretty easy and track power going
through the system in whatever units are appropriate. Systems could
start dropping off line or degrading (TC gyro?), radio displays could
start dimming/flickering, etc. (do they do that?) when the power drops
sufficiently.

Yes, and the property system makes it conventine to fire off faults
in a variety of ways. We could have external scripts that could set
up standard training scenarios. There are lot's of possibilities.
Regards,
Curt.
