PRODUCT OVERVIEW

The Health Management Unit (HMU) is a multi-function LRU that is capable of recording full-flight data, performing aircraft/engine condition monitoring, generating reports based on recorded data and offloading the data and reports to a remote ground station. The HMU will be integrated with the aircraft’s avionics systems, including the ARINC 664 network, and will be reporting maintenance related data to the Onboard Maintenance System (OMS) and aircraft condition monitoring advisory/info messages to be displayed in the Crew Alerting System.
The fundamental function of the HMU is to acquire and record parameters as outlined in the requirements section of this document. Data can be collected from the ARINC 429 and ARINC 664 input ports to be stored in resident non- volatile memory. The user can program reports that will monitor data in real time and trigger at defined conditions to capture data into recordings.
The HMU mounts in the forward Avionics Bay. The mounting mechanism is of a tray containing two ARINC 600 style ratchet latches that secure the HMU. The HMU has physical interfaces to the Primary Avionics via ARINC 664 and A429 buses, the electrical system via two DC power buses and a battery bus, the landing gear system via a hardwire discrete, and the Aircraft Network Switch (ANS) via standard Ethernet interface.
