Refer to AC43 but measure anyway.
Who knows what the German glider manufacturers do with wiring.

Hi Bob
Many thanks for your quick reply.
I realise that the size of the wiring comes into
it but I was working on the assumption that
the electronic specialists amongst us would know
what wiring the manufacturers usually
use for this applications.
BTW, Iâm not blaming the wiring, I just need
to arrive at a realistic figure for the offset in
my LX 9000.
Kind regards
Bernard

In order to calculate the voltage drop, we
would need to know the exact conductor size of the wiring.
Of course the circuit is actually going to be 22m in length.
You can (fairly) easily measure the voltage
drop with a voltmeter, to measure the voltage
at both locations while the load is applied.
Normally one would not expect a significant
drop at 0.9 A over 11m of a wire chosen carefully for the job.
However, all joints in the wiring, including
switches and breakers need to be considered, before blaming the wiring.

Good morning all
Today I have a question for the electronic specialists on this forum.
My new ASH 30 Mi has approx. 11m of electrical
cable between the avionics battery in the top
of the fin and the front instrument panel.
What voltage drop can be expected at the panel
if the combined avionics draw approx. 900 mA?
This information would be helpful to properly
adjust the voltage offset in the LX 9000.
Many thanks in advance for your help and assistance.
Bernard
