INTERCOM SYSTEM (ICS) ISOLATION

The intercom system (ICS) provides four (4) isolation
modes: ALL, PILOT, COPILOT and CREW. The desired
mode can be selected or deselected using the PILOT and
COPLT keys.
The possible ICS isolation states are summarized in the
table below. Table 6A.3.3 summarizes the ICS operation
for the four (4) ICS isolation modes and telephone distri-
bution.
PILOT Mode
PILOT mode is selected when only the PILOT key
is annunciated. In PILOT mode, the pilot can hear the
selected radios, the copilot can hear MUSIC 1, the pas-
sengers can hear MUSIC 2, and the copilot and passengers
can communicate with each other.
COPILOT Mode
COPILOT mode is selected when only the COPLT key
is annunciated. In COPILOT mode, the copilot is isolated
from everyone else. The pilot and passengers can hear the
selected radios and communicate with each other. In this
mode, the pilot can hear MUSIC 1, while the passengers
can hear MUSIC 2.
