[Flightgear-devel] turn indicator assumes 24 volt electrical system

[Dave P. <ski...@mi...>]

After I completed the pa24-electrical.nas, I noticed the turn indicator 
was always indicating a turn to the left, even sitting still on the 
ground.  When I looked at the property 
/instrumentation/turn-indicator/indicated-turn-rate was sure enough 
indicating about -0.3 while the spin was about 0.5.  I looked at the 
huricane (also has a 12 volt electrical system) and it showed a similar 
problem.  So I looked at turn_indicator.cxx (the source) and it appears 
it assumes a 24 volt electrical system (it normalizes the power by 
dividing py 24.0).  This file was written by David Megginson in 2003. 

David, would it be possible to have this routine get the normalization 
voltage from the electrical system used by the model?  I don't see any 
such value in the property tree (an ideal_volts such as is defined by 
the nasal electrical system).

This impacts other AC such as the huricane that do not have a 24 volt 
electrical system.
Thanks in advance,
Dave Perry
