What does the term "Static Wicks" refer to in aviation?

The term "Static Wicks" refers to a means of discharging static electricity in aviation. These small, lightweight devices are typically attached to the trailing edges of an aircraft's wings, tail, and sometimes other surfaces. Their primary function is to provide a path for static electricity to safely dissipate into the atmosphere, which helps to prevent the accumulation of static charge that can interfere with onboard instruments and communication systems.

When an aircraft flies through the atmosphere, it builds up static electricity due to friction with the air, especially in turbulent conditions. If not properly managed, static electricity can lead to issues such as radio interference and inaccurate readings from various navigation and communication instruments. By using static wicks, the aircraft minimizes the risk of these problems, ensuring safe and effective operation during flight.
