The Model FA5000 CVR is housed in ARINC 404A, 1/2-ATR short case. The Shielded
Housing and Crash Survivable Memory Unit (CSMU) are painted international orange.
Two reflective stripes are located on the CSMU.
The FA5000 consists of a chassis, two Printed Wiring Assemblies (Aircraft Interface PWA,
and Main Processor PWA), and the Crash-Survivable Memory Unit (CSMU). The CSMU
contains the flash memory used as the recording medium. An Underwater Locator bea-
con (ULB), also referred to as an underwater acoustic beacon, is mounted horizontally on
the front of the CSMU and is also used as the recorder’s carrying handle. The ULB
meets or exceeds the requirements of FAA TSO–C121b and TSO-C142a and is equipped
with a battery that has a life expectancy the same as the replacement date on the bea-
con. The Ground Support Equipment (GSE) connector is located on the front of the
FA5000 . This connector provides the interface from the recorder to GSE Ethernet con-
nection for checkout of the recorder, or to transfer data to a readout device. The FA5000
is connected to aircraft wiring via a 57-pin, DPXB-style connector.
The Cockpit Voice Recorder (CVR) function simultaneously records four separate chan-
nels of cockpit audio, converts the audio to a digital format, and stores the data in a mem-
ory. This CVR is available in in voice recording configuration of 120-minute. This CVR
configuration records a minimum of 120 minutes of high quality audio from the following
four cockpit audio inputs:
Channel 1: Cockpit Spare Audio Input (3rd Crew Member, Public Address System)
Channel 2: Co-Pilot’s Audio, Boom, Mask, and Hand-Held Microphone Input
Channel 3: Pilot’s Audio, Boom, Mask and Hand-Held Microphone Input
Channel 4: Cockpit Area Microphone (CAM) Input
The FA5000CVR records a minimum of 2
−
hours of all audio channels (1
−
4) in four sepa-
rate High Quality data streams. Table 1 illustrates the recording specifications for the
cockpit audio input and channels. The audio inputs are conditioned, amplified, and
equalized. The resulting signals are converted to digital pulse code modulation (PCM)
data.
