Static Discharger - Wikipedia
Static dischargers are not lightning arrestors and do not affect the likelihood of an aircraft being struck by lightning. Static dischargers will not function if they are not properly bonded to the aircraft. There must be a conductive path from all parts of the airplane to the dischargers, otherwise they will be useless. ... Read Article
