Aircraft Electrostatic Discharger

Aircraft Electrostatic Dischargers, also known as static wicks or static discharge wicks, are devices used on aircraft to safely dissipate static electricity that builds up during flight. They are part of the supply class Fuses, Arrestors, Absorbers, and Protectors in the supply group Electrical and Electronic Equipment Components.

Static electricity can accumulate on an aircraft due to various factors such as friction between the aircraft and the air, or from atmospheric conditions. If not properly discharged, this static electricity can interfere with the aircraft's electronic systems, disrupt communication and navigation equipment, and even pose a risk of ignition in fuel tanks.

Aircraft Electrostatic Dischargers consist of metal or carbon fiber rods or strips that are strategically placed on the aircraft's surface. These wicks are designed to provide a low-resistance path for the static electricity to flow from the aircraft to the surrounding air. By doing so, they prevent the buildup of static charges and ensure the safe operation of the aircraft.

The number and placement of static wicks on an aircraft are carefully determined based on factors such as the size and shape of the aircraft, as well as the anticipated static charge buildup. They are typically installed on the trailing edges of wings, tail surfaces, and other areas where static charges tend to accumulate.

Aircraft Electrostatic Dischargers are essential components for maintaining the safety and performance of aircraft. They help to protect the aircraft and its systems from the potentially harmful effects of static electricity.
