CSeries Health Monitoring To Change Maintenance Activities

The system designed to collate, analyse and transmit performance data for the CSeries has been hailed as “revolutionary” by Graham Webb, vice-president of Pratt & Whitney Commercial Engines.

The system designed to collate, analyse and transmit performance data for the CSeries has been hailed as “revolutionary” by Graham Webb, vice-president of Pratt & Whitney Commercial Engines.

In an announcement yesterday Bombardier and P&W confirmed that they had collaborated in designing a new aircraft health management system (AHMS) for the CSeries.

It will, according to Rob Dewar, VP of the CSeries programme at Bombardier, be able to provide real-time monitoring of all the aircraft’s systems critical to lowering maintenance costs.

Webb said “CSeries operators will be able to immediately review the performance of their aircraft... This is truly revolutionary and will enable operators to maximise their fleet performance, while optimising their maintenance and reliability expenditures.”

The system will use P&W’s eFAST data transmission technology to send data collated and analysed onboard by the CSeries’ health management unit, which monitors systems, including: avionics, braking systems, engines, electrical systems and auxiliary power units.

Rob Dewar said: “This state-of-the-art tool, which was specifically designed for the CSeries aircraft, has the power to change how airline maintenance crews manage their activities, resulting in fewer mechanical delays and superior dispatch reliability.”

According to P&W, its eFAST system automatically downloads, processes and stores data, before uploading to a customer portal, providing “near real-time data acquisition and transmission”.

The AHMS is currently in the “detailed design phase”, but Bombardier says it will include an on-board maintenance system which will manage fault messages from all the aircraft’s systems during flight. When on the ground the AHMS will then performs a detailed analysis of the on-board data.

Bombardier has also confirmed that while the AHMS has been designed for the CSeries the OEM is considering whether it could be installed on other aircraft including those already in service.
