Designed to meet the data monitoring requirements of the B747-400, B767, B757, B737, MD-11 and A310 aircraft, the Teledyne Data Management Unit (DMU) is a powerful data processor system that allows airlines to customize their own ACMS programs.

The Teledyne DMU accepts data from a variety of aircraft systems and airborne computers, such as the Flight/Central Management Computers (FMC/CMC), Air Data Computers (ADC), etc., to perform aircraft/engine and flight performance monitoring and analysis. The DMU is also programmed to monitor critical data and compare those data values to pre-defined normal operating limits. In the event that an engine or an aircraft parameter is out of those defined limits, an exceedance arises and a report is triggered. The report will capture all the relevant aircraft and engine information associated with the exceedance, as pre-defined by the airframe and engine manufacturers, and the operator.

The DMU works as a central hub, providing data output to various systems. It is capable of channeling reports to the Multifunction Control Display Unit (MCDU) and/or the cockpit printer, as well as to the Airborne Data Loader (ADL), the Optical/Wireless Quick Access Recorder (OQAR/WQAR), or the ACARS Data-Link system for transmission to the airline’s ground based maintenance center.
