C. Ground Requirements
(1) General
(a) Proper grounding is a key factor in ensuring proper system operation under
normal conditions, high intensity radiated electromagnetic frequencies (HIRF),
and lightning environments. You must obey this section to satisfy these
requirements.
NOTE:
HIRF and lightning requirements dictate that the shielded wires meet
the requirements of paragraph 2.C.(3). Installation of this system into
aircraft manufactured prior to the FAA requirements adheres to these
practices whenever feasible.
(2) Chassis Grounding
(a) All rack mount/remote mount units are electrically bonded to the airframe. This is
done by making sure the mating surfaces between the LRU mounting tray (or
LRU mounting feet if a tray is not used) provide a low impedance (< 0.1
Ω
)
electrical path.
