How many static wicks are on the elevators?

• A. Five
• B. Six
• C. Seven
• D. Eight

Answer: (B)

Static wicks provide a controlled path to discharge built‑up static electricity from the airplane, preventing radio interference and instrument errors. They are placed along the trailing edges of surfaces where charge can accumulate, including the elevators. For this aircraft, there are three static wicks on each elevator trailing edge, totaling six on the elevators. This distribution ensures even discharge along the entire trailing edge, reducing the chance of localized charging near the tail and keeping avionics and communications reliable. The exact count comes from the aircraft’s design and maintenance documentation, so this six-wick arrangement matches the official specification.
