Figure 3-5. Aircraft Grounding
(b) Because signal grounds are low currents, multiple signal grounds can be
connected to remote aircraft terminal blocks other than the central grounding
blocks as long as these remote terminal blocks are isolated from ground. The
various remote signal ground blocks must all be grounded only at the aircraft
central grounding point. If 10 signal grounds are connected to a remote terminal
block, a minimum of one grounding wire must be run from this terminal block to
the aircraft central grounding point.
