Model FA2100 CVR Cockpit Voice Recorder
Refer to Figure 2 for this discussion. The FA2100 CVR is a Line Replaceable Unit (LRU) that
simultaneously records four separate channels of cockpit audio, converts the audio to a digital format,
and stores the data in a solid state memory. The FA2100 CVR is available in two recording
configurations: 30-minute, Part Number 2100–1010–( ), and 120-minute, Part Number 2100–1020–( ).
Both configurations record a minimum of 30 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
Part Number 2100–1020–( ) records a fifth internal audio stream for a minimum of 120 minutes. This
fifth internal audio stream is a standard quality recording of the combination of the Pilot, Co-Pilot, and
Public Address or Third Crew Member audio inputs. Part Number 2100–1020–( ) also records a sixth
audio stream, a standard quality recording of the Cockpit Area Microphone (CAM) audio input, for a
minimum of 120 minutes. (Table 2 illustrates the recording specifications for the cockpit audio input and
combined channels.) The audio inputs are conditioned, amplified, and equalized as necessary. The
resulting signals are converted to digital pulse code modulation (PCM) data.
The FA2100 FA2100 CVR can record Greenwich Mean Time (GMT) Time via the ARINC 429 GMT
input and can record rotor speed data via the Rotor Speed input.
In ARINC 757 installations, the CVR Fault Line provides continuous status of FA2100 CVR operation.
It may be connected to an annunciator or to an aircraft central maintenance computer.
At startup, the FA2100 CVR initiates a Built-in-Test (BIT) and then continuously monitors itself for fault
conditions.
