Static dischargers (also known as static wicks or static disch | ✈️Aviation English

Static dischargers (also known as static wicks or static discharge wicks) are installed on the trailing edges of aircraft, including ailerons, elevators, rudder, wing, horizontal and vertical stabilizer tips. Fitted on almost all civilian aircraft today, they are high electrical resistance devices with a lower corona voltage than the surrounding aircraft structure. They control the corona discharge into the atmosphere.They are used on aircraft to allow the continuous satisfactory operation of onboard navigation and radio communication systems during precipitation conditions. Precipitation static is an electrical charge on an airplane caused by flying through rain, snow, ice, or dust particles. When the aircraft charge is great enough, it discharges into the surrounding air.
