The management team at Bombardier (mostly former aviation industry management types) must have realized months ago when they took over that this company had numerous aircraft, both business and commercial, that were directly competing with each other. Never mind their industry competitors.
That reality needed to be addressed. It’s taking time but it certainly seems like things are being addresssed by them.
I think what they’re doing or at least seem to be doing, is consolidating into one version of Bombardier Aerospace. They seem clearly to be focused on the Global Vision and New Generation Challenger ‘50’ Series business Jets. 650 and 350. Learjet is the orphan that never really found a home.
The Dash 8 Series has paid its’ way and found a seat in the aeroplane hall of fame but, Regional Airlines will no longer order these aircraft types in large numbers as they did in the past and Bombardier knows that. Embraer doesn’t, if they’re seriously considering the introduction of a ‘clean sheet’ turbo prop. But good luck to them if they do.
Success has not found the C series yet. The jury will be out for awhile on that.
