How is static charge created on an airframe?
Friction between the aircraft and air molecules, snow and/or ice crystals
What is the purpose of static wicks?
Facilitate the discharge of static electricity
What is bonding?
Ensuring all parts of the aircraft are electrically connected
What does bonding prevent?
Radio interference ‘crackle’ or ‘hiss’
Why must the aircraft be grounded/earthed when on the ground?
To prevent a spark being generated e.g between the aircraft and a fuel nozzle
