3.15 Internal Recorder
The Intercom Recording System is a digital recording system allowing automatic storage
and playback of aircraft radio traffic.
Operating as a continuous loop recorder, (last message received will be the first heard),
the recorder has 40 seconds of recording time, or up to 8 messages. With its own built in
voice-activation circuit, there are no buttons to press to start recording. The system
automatically begins to record the instant the radio becomes active. Only the com radio
selected for transmit is recorded, and only the pilot and copilot will hear the playback
audio. If the radio becomes active during playback, the playback will stop, and it will not
record this communication.
3.15.1 PLAYBACK
Recording is automatic. To play back the last recorded message, press and hold the Com
Receive pushbutton associated with the selected radio transmitter for about one (1)
second. The recorded audio will begin to play. You can either wait for the message to
finish playing before accessing the prior message, or cancel the playback. To cancel the
playback, press and hold the playback button for two seconds. The next time the button is
pressed for one (1) second, the prior message will be heard.
The playback will stop whenever there is more incoming selected com audio, and the
message you were hearing can be replayed from the beginning by pressing the Com
receive button again.
All messages are erased when you change the selected transmitter.
A remote playback button may be installed.
