What are the five exits located on the CRJ 550?

The CRJ 550 is equipped with a total of five exits that enhance its safety by providing multiple avenues for egress in emergencies. The correct response lists all of these exits accurately.

These exits include the Main Cabin Door (often referred to as the MCD), which is typically used for boarding and deplaning passengers. Additionally, there are two Overwing Exits - one on the left (Overwing A/CL) and one on the right (Overwing A/CR), designed for use in emergencies to facilitate a quick evacuation. Lastly, the Ground Service Door (GSD) provides access for ground crew and maintenance. The Crew Escape Hatch, located above the cockpit, also allows pilots to exit the aircraft in emergency situations.

The inclusion of all five exits in the answer reflects an understanding of the aircraft's design and emergency preparedness, which is critical when evaluating aircraft safety features and operations. Recognizing these specific exit points is essential for ground crew, flight attendants, and pilots, as they play a vital role in passenger safety during both normal operations and emergencies.
