Which exit type is not found on the 737-800 series A/C?

In the context of the Boeing 737-800 series aircraft, the design includes various types of exits to facilitate emergency evacuations. The aircraft features over wing exits, which are standard in many commercial jets, as well as emergency slide exits that enable fast egress in emergencies. Additionally, the 737-800 is equipped with dual door exits, typically located at the front and the rear of the cabin for efficient passenger flow.

The type of exit that is not part of the 737-800 configuration is the single door exit. The design primarily emphasizes dual exits to enhance safety and ensure quick evacuation options for passengers. By incorporating multiple exits, the aircraft design adheres to stringent safety regulations, allowing for effective emergency management.

In short, while over wing exits, emergency slide exits, and dual door exits serve specific purposes in enhancing safety and efficiency, the absence of single door exits in the 737-800 configuration is indicative of the aircraft's design philosophy focused on maximum passenger safety and regulatory compliance.
