3. SYSTEM DESCRIPTION
The Model FA5000 Cockpit Voice Data Recorder systems leverage from the existing
FA2100 family of recorders, capitalizing on already developed components to the maxim-
um extent possible. As a minimum, the development of Next Generation systems will
maximize re-use of established software, and re-host this software onto new, higher per-
formance internal processing components. .
The main recorder consists of two main internal boards: the Processor Board PWA and
the Aircraft Interface PWA. The PWA interconnect arrangement is shown in the figure
above. The Processor Board includes the GSE interface (RJ45), the CSMU interface, a
right angle backplane connector, and an expansion card interface. The expansion card in-
terface supports the Video Image and Capture Card PWA. The Aircraft Interface PWA
provides a 55 pin MIL-C-39888, Series II connector (16-35 shell size-insert arrangement)
for connectivity to the aircraft, a connector to mate to a right angle connector on the Pro-
cessor Board PWA, and a video connector for cabling to the Video Image and Capture
Card PWA.
The unit provides the flexibility to be factory configured into a crash-survivable combina-
tion cockpit voice recorder/flight data recorder (CVDR). This unit converts analog cockpit
audio signals to digital format and provides large capacity digital memory storage for digit-
al data recording and DataLink messages. The unit also samples and records ARINC 717
aircraft flight data. The recording medium is protected by a crash-survivable enclosure
capable of withstanding environmental requirements set forth in ED-112.
The unit interfaces to Ground Support Equipment (GSE) via industry-standard network
protocols (Ethernet, Wireless), with the GSE operator interface via an ordinary web
browser.
The software running on the Model FA5000 will process the incoming audio data, flight
data, and DataLink messages into packets that get stored in the CSMU. The software will
also provide built-in test functionality that will automatically perform checks of the hard-
ware and software to indicate whether the system is operating normally. The user will be
able to download recorded data via an Ethernet-based web browser. The web browser
will also let the user monitor real-time data and other system functions.
The following is a list of the inputs and outputs for the CVDR system. See Figure 3 –
CVDR Block Diagram for the inputs and outputs of each recorder type.
