Where are in-flight static eliminators installed?

• A. On wing tips and tail assembly trailing edges.
• B. On landing gear struts.
• C. Inside the cockpit window frames.
• D. On the engine intake.

Answer: (A)

Static discharge wicks provide a controlled path for accumulated static electricity to leave the aircraft and enter the passing air. Placing them on the trailing edges of wings and on the tail assembly puts the discharge points in fast-moving air and away from sensitive systems, which helps keep radio and navigation equipment free from static interference while minimizing drag and erosion. Locations like landing gear struts, inside cockpit window frames, or engine intakes aren’t effective for this purpose and can lead to wear or interference, so the most reliable placement is along the wing tips and the trailing edges of the tail.
