The Airbus A220-100 (previously Bombardier CS100) jetliner is a single-aisle, long-range passenger aircraft developed by Bombardier Aerospace. The CS100 can accommodate 100 to 125 passengers based on the seating configuration.

Bombardier Aerospace launched the CSeries aircraft programme in July 2008. The CSeries includes two models: CS100 jetliner with options of 100 to 125 seats, and the CS300 jetliner with 130 to 145 seat layouts.Systems integration began at the Complete Integrated Aircraft Systems Test Area (CIASTA) in April 2012. The first flight was completed at Montréal -Mirabel Airport in Québec in September 2013.

The aircraft obtained a type certificate from Transport Canada in December 2015. The aircraft secured type validation by European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) in June 2016. The first aircraft was delivered in July 2016.

The aircraft was renamed A220-100 following the sale of 50.1% stake of the Bombardier C Series to Airbus in July 2018.

JetBlue placed an order for 60 A220-300 aircraft in July 2018 and the deliveries are expected to begin in 2021.

Airbus booked approximately 400 A220 orders as of November 2018.

Design and construction of A220-100

The CS100 aircraft incorporates a clean-sheet design. The airframe is made of advanced structural materials for achieving weight savings. The fuselage is made from aluminium. Advanced composite materials have been used for the empennage, rear fuselage, nacelle and wings.

Advanced materials are composed of advanced composites (46%), aluminium-lithium (24%), standard materials (21%), titanium (8%), and steel (1%).

Bombardier aircraft light deck

“The aircraft features wider aisle for quick boarding and de-boarding of passengers.”

The CS100 aircraft is equipped with a Rockwell Collins Pro Line Fusion integrated avionics system. The advanced flight deck accommodates two-member flight crew, comprising a pilot and co-pilot. It incorporates large LCD displays, dual-flight management system, dual cursor control devices, navigation, communications, surveillance, engine indication and crew alerting system (EICAS), and aircraft maintenance systems.

The flight deck can be equipped with an optional dual electronic flight bag, single or dual head-up display (HUD), and Cat IIIb autoland capability. The line-replaceable modules (LRB) are housed in two physically separated cabinets to ease the maintenance and optimise weight.

CS100 jetliner cabin

The CS100 aircraft features a five-abreast cabin delivering more seat width for every passenger. The extra large windows offer better view angles. The cabin offers highest overhead bin volume per passenger compared with that of the currently in-service narrow-body aircraft. The aircraft features a wider aisle for quick boarding and de-boarding of passengers.

The CS100 offers a variety of seating options to meet the requirements of the airlines. The interior can be configured for single-class seating (110 seats), mixed-class (100 seats), and high-density class (125 seats) seating.
