What is the model number for the CRJ 900?

The model number for the CRJ 900 is recognized as CL-600-2D24. This identifier is significant because it uniquely distinguishes the CRJ 900 from other aircraft in the Bombardier CRJ series, such as the CRJ 700 and CRJ 1000, which have different model numbers. Specifically, the "2D24" suffix indicates specific configurations and capabilities that differentiate the CRJ 900 from similar models, thereby affirming its alternate designation.
