Location on the airframe of an electrostatic discharger enables them to serve a role as a lightning conductor and provide protection against arcing for the surrounding aircraft structure.
Static dischargers are replaceable and may be mounted on supports that are attached to the aircraft structure in such a way as to ensure adequate electrical contact.
Different types of static dischargers are used to alleviate different problems on various types of aircraft. This means a small general aviation aircraft flying at lower speeds will not use the same type of device as a commercial airliner or business jet.
Cobham manufacture a range of wire and carbon miniflex and miniprobe static dischargers and bases for all airborne applications.
