Digital Flight Data Acquisition Unit

The Teledyne Controls' DFDAU/DFDMU acquires aircraft data via digital data bus and analog inputs, and formats that information for output to the mandatory Flight Data Recorder in accordance with requirements of regulatory agencies. In addition to the mandatory function, most Teledyne DFDAU's have a second processor and memory module which enables them to perform a limited amount of Aircraft Condition Monitoring System (ACMS) functions / reports such as long-term trend data and aircraft / engine monitoring. Also, the DFDAU provides data and pre-defined reports to the cockpit printer or display for the flight crew, directly to the ACARS Management Unit for transmitting the ground, and to a maintenance recorder (QAR) or Wireless GroundLink® for recording / storage / transfer of raw aircraft data.
