Aircraft static dischargers, the small rods often seen on wingtips, dissipate built-up static electricity to reduce radio frequency interference and other electrical hazards.
The Aviation Consumer notes that airflow over an aircraft generates static charge and that electrostatic discharge can produce RFI that degrades VLF, HF and VHF communications and navigation receivers.
The Aviation Safety Blog of the Naval Safety Command warns electrostatic discharge can also shock ground personnel, damage aircraft subsystems, or in military contexts cause uncommanded ordnance activation or release.
Engineers use static dischargers—commonly called static wicks—to bleed charge safely into the atmosphere, helping maintain radio operation and reduce electrical hazards even though extreme events such as lightning strikes remain a separate concern.
