During expedited deplaning on the CRJ 200, through which door should passengers exit?

During expedited deplaning on the CRJ 200, passengers exit through the MCD, which stands for Main Cabin Door. This door is designed as the primary exit for boarding and deplaning, making it the most efficient route for passengers to exit the aircraft quickly in situations where such a procedure is necessary. Utilizing the MCD helps ensure a streamlined process, especially when time is critical, as it is located in the middle of the aircraft, allowing easy access for all passengers from both the front and rear sections. The design and typical operations of the CRJ 200 support the MCD's use, ensuring safety and quick response during deplaning.
