GENERAL
The Cockpit Voice Recorder (CVR) records the last
30 minutes of cockpit communications and sounds
using a four channel endless magnetic tape. The
recorder with its crashproof housing is installed in
the rear compartment.
The CVR operates continuously as soon as L BAT
and ESS AVION switches are set to ON.
The CVR records audio communication directly
from the Remote Electronic Unit (REU) on three
separate channels for pilot, copilot and PA/Cabin
Interphone. The fourth channel records sounds
picked up with the cockpit area microphone in the
overhead panel.
The whole tape can be erased in a few seconds
provided aircraft is on ground and gust lock set.
The recorder is provided with an underwater locator
beacon which is automatically started when sub-
merged in water. The locator is battery powered
and will send out acoustic signals for 30 days.
An Inertia switch will switch off the CVR saving the
records if the aircraft longitudinal G

load exceeds
2.5 G.
