How many static wicks are on the tail?

• A. 10
• B. 11
• C. 13
• D. 15

Answer: (C)

Static wicks are the little discharge devices that give static electricity a safe path to escape from the aircraft as it flies. They’re placed on trailing edges where airflow carries charge away most effectively, with the tail having multiple wicks along the vertical and horizontal surfaces to cover the long trailing edges there. The exact number of wicks on the tail isn’t chosen arbitrarily—it’s fixed by the aircraft’s design and documented in the maintenance and configuration materials for that specific model and operator. So this question is really about knowing the tail’s prescribed wick count for this CRJ-550 configuration. The correct option is the one that matches that official count, which aligns with the aircraft’s documented setup; the other numbers don’t reflect the sanctioned tail wick configuration. For the precise value, refer to the aircraft’s equipment list in the maintenance manual or the operator’s Quick Reference/maintenance documentation.
