4. Electrostatic discharges in aeronautics
In the aeronautical field, aircraft are likely to be charged either by influence when passing close to a thunderstorm, or by triboelectricity: atmospheric precipitation (rain, snow, dust, sand, etc.) generates electrostatic charges on the fuselage, wings, radome and cockpit. These charges are a function of atmospheric conditions, but also of the aircraft's size and speed. This charging phenomenon is known as "P-Static" (static precipitation: ) and can give rise to various types of discharge, which can disrupt on-board electronics without jeopardizing aircraft safety. These...

Regulations
Existing regulations cover the risks of explosion and/or fire that can be caused by electrostatic discharges in certain industrial environments. See European Directive 94/9/EC or ATEX 137 (for explosive atmospheres) for equipment and 1999/92/EC or ATEX 100A for worker safety.

Statistical and economic data
It is estimated that at least 60% of faults encountered in the electronics industry are due to electrical overload (EOS: Electrical Over Stress) or electrostatic discharge (ESD), and in this case 70% of faults are due to ungrounded personnel. Personnel are becoming increasingly aware of the ESD risk, but at the same time, the evolution of technology (continuous reduction in the size of electronic components)...
