Bombardier admits it faces a dilemma over whether to bring its in-test CS100 to Farnborough.
Mike Arcamone, president of commercial aircraft for the Canadian airframer, says his sales team would "love" to have the CSeries at the year's biggest air show but that pressing on with the delayed flight test programme may be more important.
"We cannot definitely say we will stop [flight testing] because of Farnborough," Arcamone told Flightglobal after addressing the Aviation Club in London on 27 March.
Bombardier has three CS100s in flight-test and expects to have a fourth airborne well before Farnborough in July. However, six months after first flight, several key milestones remain to be completed. For instance, there is uncertainty over whether, or if, Bombardier has flown the twinjet with its fly-by-wire flight control system in normal mode, with envelope protection activated. Arcamone will only say that successive flights have been "opening up the envelope". Certain aspects of the certification process can only be carried out in this mode.
