Montreal-based Bombardier says that it will release more pictures and a video on 23 August.
The roll-out comes shortly after the CSeries flight test programme was extended to 22-months from this August through May 2015 by Transport Canada, in an Aeronautical Information Products (AIP) Canada update released by NAV Canada dated today. The programme was previously 18 months from May through November 2014.
Bombardier maintains - as it has for the past few weeks - that first flight will occur in the "coming weeks".
The aircraft, a CS100 known as FTV-1, began low-speed taxi tests on 16 August and is expected to begin high-speed taxi tests shortly.
