Teledyne Controls' 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 to an internal PCMCIA or magneto optical disk recorder.

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.

Teledyne's DFDAUs are service proven systems that have been adopted by hundreds of commercial and military operators worldwide.
