How many doors does the Embraer E190 have?

The Embraer E190 is designed with four passenger doors and two service doors, making the configuration in the choice correct. Specifically, the aircraft features two doors located in the front of the fuselage, which are typically used for boarding and deplaning passengers, and two additional doors located further back for supplementary access. The service doors are strategically placed to allow ground personnel efficient access to the aircraft for loading supplies, maintenance, and other operational needs.

In commercial aviation, the door configuration on an aircraft is crucial as it directly impacts passenger boarding efficiency and safety during emergencies. In the case of the E190, this design not only enhances passenger flow but also complies with safety regulations that govern exit accessibility and evacuation procedures.
