How many seats are located in the flight deck of the ERJ 175?

The flight deck of the ERJ 175 is designed to accommodate two pilots, which is why the correct answer reflects a total of two seats. The cockpit configuration caters specifically to the needs of the pilots during flight operations, ensuring that they have sufficient space and required instruments at their disposal. The design emphasizes efficiency and focus on critical flight tasks, which is why only two seats are necessary in this area.

The options suggesting more than two seats, such as three, four, or five, may imply a misunderstanding of the intended use of the flight deck, which primarily supports the roles of a captain and a first officer. There are no additional seating arrangements for crew members in the flight deck of the ERJ 175, thus confirming that the only seats present are dedicated to the pilots operating the aircraft.
