  • Aircraft Static Dischargers

    Aircraft Static Dischargers

    Static dischargers, commonly known as static wicks or static discharge wicks, are installed on the trailing edges of aircraft, including (electrically grounded) aileronselevatorsrudderwing, horizontal and vertical stabilizer tips. Fitted on almost all civilian aircraft today, they are high electrical resistance (6-200 megaohm) 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 (p-static) conditions.

    The main purpose of an electrostatic discharger is to improve the dispersal of accumulated aircraft static charges in an effort to reduce the resultant radio interference.

    They are unobtrusive for the most part, and sometimes they are overlooked on a preflight inspection. But static wicks—the small wires protruding from the trailing edge of an airplane’s wing or empennage—serve an important function in the air.

    Friction generated as an aircraft moves through the air can cause a buildup of static electricity. The wick, which resembles a wire, transfers that electricity back into the atmosphere to prevent it from interfering with navigation and communication radios. In the unlikely event your trainer should get struck by lightning in flight, the static wick would work to dissipate the energy from that strike.

    Look at a static wick and you’ll see a cord-like structure riveted directly to the skin of the trailing edge to make metal contact. It may be wider where it connects to the airplane than at the end.

    While you’re taking that closer look, ensure that the static wick is neither broken nor excessively frayed—particularly if you’re planning to fly under instrument flight rules.
