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...
