How many static wicks are installed on the wings of GoJet planes?

• A. 6
• B. 9
• C. 12
• D. 15

Answer: (B)

Static wicks are there to bleed off built-up static electricity from the airframe into the surrounding air, keeping radio communications clear and protecting sensitive avionics. They’re placed along trailing edges where airflow helps carry the charge away, and the total number is chosen by the aircraft manufacturer to balance effective discharge with weight and drag. For GoJet’s CRJ-550 fleet, the wing-wick configuration is set by the manufacturer to provide adequate static dissipation without adding unnecessary drag or maintenance complexity. The correct option reflects that specific GoJet factory configuration. Choosing too few could leave some static accumulated, potentially affecting communications; choosing more than designed would add needless drag and weight. The listed count in GoJet’s configuration represents the right balance for its wings, which is why that option is the best choice.
