The Aircraft Health Monitoring System is a ground-based monitoring and analysis system primarily using ACARS as source data, integrated with QAR data. By analyzing real-time ACARS data and applying post-flight QAR data, the system enables the monitoring of the aircraft's operational status.

The service includes providing customers with access to COMAC's health management system. To use the COMAC Health Management System platform, the customer must authorize the data link service provider to transmit the ACARS message data of relevant flights to COMAC in real time and provide the necessary message parsing specifications as required.

The goal of the service is for customers to use the COMAC Health Management System to monitor the status of delivered aircraft and track faults.

Customers benefit by improving the timeliness of their perception of the aircraft’s technical status information, helping to identify and confirm aircraft-related faults early.
