What does CRJ stand for in the aircraft model name?

The term CRJ stands for Canadian Regional Jet. This designation is indicative of the aircraft's origin and its intended market segment. The CRJ series was developed by Bombardier, a Canadian company, and is specifically designed to serve regional airline markets. By focusing on regional operations, the CRJ models enable airlines to offer point-to-point service in markets that may not support larger aircraft. This adaptability to regional demand has made the CRJ a popular choice among airlines operating in both domestic and international markets.

The other options misrepresent the aircraft's branding or the function of the aircraft. For instance, while Cessna produces various aircraft, it is not associated with the CRJ series. "Commercial Regional Jet" and "Carrier Regional Jet" do not accurately reflect the aircraft's designation or its Canadian origins, which is a key detail in understanding the CRJ series.
