Which of the following is NOT a location for exits on the CRJ 550?

The main cargo door is not considered a passenger exit location on the CRJ 550. The CRJ 550 is designed for efficient passenger egress, and its defined exits are specifically designated for passenger safety and accessibility.

The other options represent actual exit locations on the aircraft. The GSD (Galley Service Door) is used as an entrance and exit point for service personnel, while the overwing exit doors (A/CL and A/CR) provide additional passenger evacuation routes in case of an emergency. Identifying these correct exit locations is crucial for both safety protocols and emergency procedures onboard, as spending time at unauthorized exits could hinder evacuation efficiency.
