The Airbus A220 started life as the Bombardier C-Series, which was the modern next generation aircraft designed to compete head to head Embraer's regional jets and supersede the successful CRJ series of jets. The fly-by-wire C-Series CS100 first flew in 2013 at the carriers factory at the Montreal Mirabel Airport. After about 3 years of testing and delays, the first example entered service with Swiss International in 2016. A stretched variant, the CS300, first flew in 2015 and entered service with airBaltic. In 2018, Airbus purchased a majority share in the program, renaming the CS100 the A220-100, and the CS300 the A220-300. Airbus also opened up an A220 line at it's factory in Mobile, Alabama in the USA. Unlike the CRJ, the A220 is primarily a mainline aircraft, despite directly competing with ERJs, and is flown by major airlines like Delta, jetBlue, and Air Canada. The aircraft has range competing with 737s, able to complete flights as long as Toronto to the US West Coast. Airbus has future plans to release a stretched variant and a VIP variant.
Currently, the following realistic add-ons are available for this aircraft:
Virtualcol A220: Prepar3Dv1-5/Microsoft Flight Simulator X
Free A220: X-Plane (lacks many features but is being updated frequently)
