Description / Abstract:
Purpose:
This document establishes the minimum requirements for the
electrical bonding and grounding of electric, avionic, armament,
communication, and electronic equipment installations for
aeronautical and aerospace applications. The bonding and grounding
requirements specified herein are to ensure that an adequate low
resistance return path for electric, avionic, armament,
communication and electronic equipment is achieved which can
withstand operating conditions and corrosion. This is essential for
the reduction of coupling of electromagnetic fields into or out of
the equipment as well as for providing electrical stability to
control the currents and/or voltages caused by static charges and
discharges and for suppressing the hazardous effects thereof.
General:
A prerequisite to effective control of electromagnetic
interference (EMI) and the hazards of electrical effects is the
establishing of a reference ground plane and the means of providing
adequate connections to it. Making a connection to the ground plane
is grounding, and the mechanical method of providing a low
impedance union between conductors is electrical bonding.
