3.3.5.2 PIL ISO (Pilot Isolation) Operation
In normal operation, the pilot, copilot, and passengers hear the same signals from the aircraft
communication system. Sometimes this is not desirable from the pilot's perspective, for instance
during communication with the tower on approach, or when discussions on the intercom would be a
distraction. Many times the copilot position is simply another passenger, and the pilot may wish to be
isolated from them.
PILOT ISO mode separates the pilot from the intercom network, allowing confidential radio
communications without interference from the copilot or passenger intercom or music. The pilot has no
ICS operation, and all signals are presented in mono format during this mode. All other users are
unaffected and continue to use the entertainment and intercom functions of the AA83-001.
While in PILOT ISO mode, the pilot maintains complete control of all the radio functions of the
intercom, and the pilot mic and TX keyline are directly connected to the transceiver. The pilot phones
are driven by the transceiver.
The copilot and passengers will be unable to monitor any transceiver activity, although they retain full
ICS and music functions. This mode is 'fail-passive', meaning that it requires no power to operate and
is the same mode the box goes into automatically when power is lost to the AA83-001. In this way,
switch over is immediate for the pilot and there is no possibility of lost communication because of a lack
of pilot action. Note that the pilot's boom mic is sent directly to the radio in this mode, and only a PTT
key input is needed to transmit.
Note: In this mode, the receive/sidetone levels may require adjustment at the audio source.
3.3.5.3 SPLIT Operation
Operation in SPLIT Mode is similar to NORM mode, but if the AA83-001 is connected as part of a multi-
unit system, the SPLIT mode allows external users to be disconnected from the AA83-001 ICS
communications without requiring adjustment of the ICS Audio level.
All users are permitted to talk to each other, listen to music, and hear all radio communications. There is
provision for an external ICS tie line load to maintain the ICS audio at the same level as in NORM mode.
3.3.6 Radio Functions
There are two PTT inputs: one each for the pilot and copilot. Activation of either PTT input connects
the user’s MIC to the radio, and activates the output PTT to the radio.
Sidetone audio input is provided from the radio, not by the AA83-001 microphone circuits. Transmit
sidetone audio utilizes AA83-001 Radio RX audio and phones driver circuits.
Radio RX/sidetone is a mono signal, but RX balance control may be adjusted to provide spatial
displacement to aid user in quick signal identification.
Note: A priority transmission feature allows the pilot to override the copilot.
