CRJ is an abbreviation for which type of aircraft?

The correct answer is the abbreviation "CRJ," which stands for "Cañadair Regional Jet." This designation refers to a family of regional jets originally developed by Bombardier, designed for short-haul flights and typically used by regional airlines. The CRJ series includes various models such as the CRJ700, CRJ900, and CRJ1000, which play a vital role in regional air transportation, enabling airlines to operate efficiently on shorter routes with lower passenger demand.

Understanding the name is crucial because it highlights the aircraft's Canadian heritage (from Cañadair) and its primary function in the regional market. The CRJ series has become synonymous with modern regional jet operation and has established itself as a key player in regional air travel.
