The Teledyne Flight Data Interface Unit (FDIU) provides operators of the Airbus A330-200/300 and A340-200/300 with the only certified capability to meet the latest mandatory Digital Flight Data Recorder (DFDR) recording requirements, including the 88 Parameter FAR 121.344, JAR-OPS 1.715 and parameters defined in the new ED112.

FDIU Capabilities:

• Acquires and formats critical flight parameters and supplies them to the external DFDR for recording in an ARINC-717 Bi-Phase data output.
• Provides an ARINC-717 Bipolar data output for an (optional) external Quick Access Recorder (QAR), with the data frame identical to the DFDR output.
• Provides a Cockpit Voice Recorder (CVR) time synchronization output.
• Allows software update via a Portable Data Loader (PDL) or a Multifunction Disk Drive Unit (MDDU).
