Teledyne data acquisition unit to aid 737 health management

Teledyne Controls has reached an agreement with Boeing to supply its Digital Flight Data Acquisition Unit (DFDAU) as a key component in Boeing’s Airplane Health Management (AHM) system for the 737NG family.

Teledyne’s DFDAU, which combines the functions of mandatory data acquisition and recording with an aircraft condition monitoring system (ACMS), is hosting a set of custom ACMS applications designed to acquire and output data into Boeing’s ground analysis tools, providing 737 operators with an advanced solution for proactive maintenance and enhanced operations.

Until now, Boeing’s AHM offering had focused on aircraft equipped with a central maintenance computer (CMC) to provide critical fault data to the Boeing AHM ground station over the aircraft’s data link. Teledyne’s DFDAU, with its embedded ACMS, will perform the CMC function, by feeding data to Boeing’s AHM diagnostic, prognostic and trending algorithms.
