Bombardier has painted one of its CSeries flight-test aircraft in the colour scheme of the type's launch customer Swiss.
The Canadian manufacturer posted a photo of the CS100 via Twitter. The aircraft (registration C-GWXZ) is the programme's fifth flight-test vehicle and the first fitted with a cabin interior.
It will be on static display at the Paris air show and will visit Swiss's base in Zurich after the event. In 2009, Swiss parent Lufthansa Group ordered 30 CS100s for the Alpine airline.
Bombardier says the CS300 that is to take part in the Paris air show's flying display arrived at Le Bourget yesterday.
Certification for the CSeries is scheduled by year-end, with entry into service due to follow during the first half of 2016.
