MAU Frequently Asked Questions
What is the role of the MAU in a flight data system?
The MAU is a standalone Line Replaceable Unit (LRU) that collects and processes flight parameters from multiple sources and outputs a clean ARINC 717 data stream to the Flight Data Recorder (FDR). It is essential for aircraft that lack a native FDAU or require data consolidation across multiple input types.
What configurations are available?
MAUs are available in 24- and 48-channel configurations, with optional Quick Access Recorder (QAR) modules. Each unit is firmware-customized to match the aircraft’s parameter list, ensuring accurate and reliable data capture.
What are the integration and certification considerations?
Each MAU is tailored to a specific aircraft configuration and parameter set, which results in a unique part number. While some installations may be supported by existing approvals, many require aircraft-specific engineering coordination. Certification pathways vary depending on the airframe, and field approvals are generally not applicable.
What enhancements are being explored?
Future capabilities under consideration include wireless data download for streamlined access and integration with Emergency Locator Transmitters (ELTs) to support enhanced emergency response and data continuity.
