Bombardier has provided no timetable for returning the CSeries test aircraft (FTV-1) to flying status while a second round of ground vibration testing continues.
FTV-1 stopped flying after completing its third flight test on 3 October. The first three tests allowed Bombardier to clear the landing gear certification and gain insight into the aircraftÂ€™s high-lift systems, such as flaps.
FTV-1 also performed a Â€œbunch of other flight manoeuvresÂ€ as the test team works to expand the flight envelope, Dewar says.
Dewar also noted that the aircraft remains in ground vibration testing, even though Bombardier said last June that such testing had been completed.
The previous round of ground vibration testing simply cleared the FTV-1 for first flight, says
Â€œIt was a decision of sequencing that we made earlier,Â€ Poutissou says on the sidelines of the Canadian Aerospace Summit in
FTV-1 demonstrated in the first three flights the stability and control that Bombardier expected, Poutissou says.
The aircraft flew all three flights in direct mode, meaning that the normal fly-by-wire control system has so far not been activated. The next round of flight tests will begin examining the normal mode of the fly-by-wire system, in which the flight computer commands the control surfaces based on inputs by the pilot.
Â€œWe are getting ready to fly the aircraft higher, faster and at a different [centre of gravity],Â€ Poutissou adds.
Although local spotters have tweeted FTV-1 is out of the hangar, Bombardier is unwilling to commit to a timetable for a return to flight.
Â€œFlight test programmes are fluid,Â€ says Poutissou. Â€œI canÂ€™t give you a time.Â€
