BBD v Boeing on First Flight: We, along with others, have wondered why Bombardier wants a clear, sunny day for first flight when Boeing flew the 787 on a rainy day in December. Was this some regulatory difference between Canada and the US, or was this a policy decision by BBD vs Boeing?
It’s a policy decision, BBD tells us. The Transport Canada flying permit is good for any weather, but the CSeries–for Bombardier–is an entirely new configuration (engines on pods under wings vs rear-mounted engines and T-Tail), new engine types, fly-by-wire and so on. So the company is being conservative. From a technical standpoint, the first flight could be on a rainy day such as that experienced by Boeing (which is tough not to have in Seattle in December).
The high speed taxi tests, followed by the shimmy and braking tests, do need a dry runway and low winds, BBD tells us.
Here’s the weather report through Tuesday at Mirabel Airport. Not very encouraging.
Meanwhile, The Toronto Star has this latest look at when the airplane may fly and comments from others.
