Testing on Bombardier's "Aircraft 0" CSeries integrated systems test and certification rig, housed in its facility in Mirabel, Quebec, has been progressing better than planned, according to the airframer.
In the lead-up to flight tests scheduled later this year, the ground rig is critical to identify and address any problems with the dozens of advanced systems being installed on the CSeries.
Of 47 unique systems tested on Aircraft 0, two have shown minor issues so far, says Robert Dewar, Bombardier's CSeries vice-president and general manager. However, Dewar declines to identify the systems that are not working correctly.
Dewar says that some problems are anticipated during the test phase, but the overall test programme is progressing more smoothly than envisioned.
"What we've confirmed so far is that all the systems actually integrate and talk together a little bit better than expected," says Dewar.
The fly-by-wire system developed by Parker Aerospace, previously a cause of concern, is performing well in ground tests, Dewar adds.
