I agree! Was not aware of the .5 limit (that's pretty strict) As you know, this could be exceeded with the smaller wires run at full capacity with lengths to the wingtips, for example. For "most" applications (trim wires, radios, etc) and circuits not near max current capacity, it shouldn't be a problem. But I agree, the voltage drop should be taken into account for proper planning.
Thanks for your input, this is a valuable piece of the analysis!
It's not that simple. The current causes a voltage drop. The longer the wire, the greater the drop. FAR requires no more than .5v drop for any circuit in the plane.
