Teledyne Controls' enhanced Digital Flight Data Acquisition Unit (DFDAU) is an integrated system that combines the functions of Mandatory Data Acquisition and Recording with a sophisticated Aircraft Condition Monitoring System (ACMS). This comprehensive system provides aircraft operators with a standardized hardware and software solution for high-power data acquisition, management and recording in an internal PCMCIA recorder.

High-Speed Data Processing and Ethernet Connectivity
Designed to meet the extensive data management requirements of newer aircraft, Teledyne's DFDAU-9X6 is the latest family of acquisition units which supports faster data processing, increased performance and higher reliability. The DFDAU-9X6 family is also equipped with optional Ethernet capabilities for high-speed transfer of data to Ethernet-based equipment, such as wireless data communication systems. The DFDAU's ACMS software is extensively flexible, allowing users to define the parameters and reports they need for flight data monitoring, maintenance, and operational efficiency, without the artificial constraints typically imposed by other software systems.

Initially introduced to the market in 2003, Teledyne's latest generation of DFDAUs are service proven systems that have been adopted by hundreds of commercial and military operators worldwide.
