COMAC and Teledyne link up for ARJ21 monitoring system

By June 19, 2018 January 16th, 2020 General News

Teledyne Controls has partnered with China’s COMAC to build a real time monitoring system (RTMS) for the manufacturer’s ARJ21 aircraft.

The first RTMS-equipped ARJ21 aircraft is expected to be delivered later this year or early in 2019. Over 450 ARJ21s have been ordered by more than 20 customers so far.

The flight data specialist’s real-time monitoring unit (RTMU) is at the heart of the system that will be used in all ARJ21 aircraft after its certification. The RTMU will provide COMAC with a state-of-the-art hardware and software solution for data acquisition, aircraft condition monitoring and data recording, says Teledyne.

“The purpose of the RTMU is to acquire and monitor the aircraft parameters,” said Richard Huang, Teledyne Controls’ director of marketing and sales for the Asia Pacific region. “If any parameters are outside of the norm, it will generate and downlink the reports via ACARS in real-time to notify the airline operator and/or the aircraft manufacturer. The operator/manufacturer can then take the appropriate action in a timely manner, supporting operational safety and efficiency.”

The RTMU also records and downlinks continuous raw data after the aircraft lands, via Teledyne’s GroundLink Comm+ systems already installed on the ARJ21. This data can be used for aircraft system condition monitoring, performance trending and operational quality assurance.

The RTMU combines the fully-programmable aircraft condition monitoring system (ACMS) processing capability of the Teledyne data management unit with the internal recording capabilities of the Teledyne quick access recorder, added Huang.
