Aeronautical static discharge device and indicator therein

摘要

A static discharge device includes a body an an electrical path carried in the body for discharging static electricity. Carried on the body is visual indicia indicating a present operational status of the electrical path to discharge static electricity effectively. The visual indicia is observable to an airplane operator or technician to quickly determine the operational or non-operational status of the static discharge device.

主权项

1. A static wick for shedding electricity from an airplane, the static wick comprising:
a body; an electrical path through the body from a base to a discharge end, the electrical path including a spiral-wound conductive element; and observable, visual indicia carried by the body indicating a present operational status of the electrical path, the visual indicia being responsive to provision of heat to the visual indicia from the spiral-wound conductive element; wherein the spiral-wound conductive element produces heat in response to degradation of the electrical path and provides said heat to the visual indicia.
