Another Key C-Series Advantage over Airbus A319"the C-Series is capable of taking off and landing at airports that Airbus aircraft are unable to use due to runway constraints.
The C-Series CS100 model is capable of taking off at maximum take off weight with just 3,999 feet of runway while landing at maximum landing weight requires just 4,400 feet. The Airbus A319 requires 7,100 feet of runway to take off at maximum take off weight. The CS100 will open up new route opportunities, especially from the new Caticlan Airport, as it carries a maximum range of 5,463 kilometres, which is unparalleled by any other aircraft in its class."
