What is the standard number of static wicks installed on the wings of GoJet planes?

• A. 6
• B. 9
• C. 12
• D. 15

Answer: (B)

Static wicks are small discharge devices that bleed off built-up electrical charge from the aircraft into the airstream. They’re placed along the trailing edges of the wings so charge can escape across the entire wing span, reducing the risk of radio interference and avionics disruption. The number and placement are chosen to provide reliable, even discharge from all parts of the wing, including near the tips and around moving surfaces like flaps.

For GoJet’s CRJ-550 family, there are nine static wicks installed on the wings. This arrangement gives good coverage across the trailing edge, maintains electrical balance between wings, and includes redundancy so a single wick failure doesn’t compromise discharge effectiveness. Fewer wicks could leave gaps in discharge capability, while more would add weight without substantially improving performance.
