Bombardier is being more ambivalent about introducing a stretched Q400 than it has in the past, stressing no timing exists for a launch or delivery.
Company vice-president marketing for commercial aircraft Philippe Poutissou made those comments during the show, explaining that Bombardier continues to both study the Q400X and engage in discussions with customers about the 90-seat aircraft.
The airframer appears less tentative about the Q400X that it has in the past. Bombardier commercial aircraft president Gary Scott in March 2009 said the company was examining a 2013-14 timeframe to offer a stretched Q400.
Currently Bombardier has four aircraft programmes in various phases of development - the Learjet 85, a new member of the Global series family, the CSeries and the CRJ1000.
Vice-president of strategy, business development and structured finance Mairead Lavery says with those programmes "there's quite a bit of engineering under way" and Bombardier continuously looks at its product portfolio to manage the location and distribution of its engineers.
Poutissou is declining to comment on a lack of orders for Bombardier aircraft from new lessor Air Lease headed by International Lease Finance founder Steven Udvar-Hazy.
During the show Air Lease has placed orders with Airbus, ATR, Boeing and Embraer.
Noting the planned 2013 entry-into-service date of the new design CSeries narrowbody, Poutissou says in the single-aisle category, Bombardier "doesn't have any aircraft available in the near term".
