What is the normal configuration of fuel tanks in the EJet series?

The normal configuration of fuel tanks in the EJet series is indeed two wing tanks and a center tank. This design is optimized for fuel storage and distribution, allowing for an efficient balance and management of fuel during flight.

In this configuration, the two wing tanks are located within each wing, supporting the aircraft's structure while providing significant fuel capacity. The center tank, which is situated in the fuselage, adds additional capacity and allows for flexible fuel management. This arrangement helps maintain aircraft stability by allowing balanced fuel distribution.

The use of wing and center tanks is standard in modern regional jets like the EJet, as it enhances the range and operational efficiency of the aircraft, making it capable of longer flights while also ensuring that fuel weight is distributed evenly across the wings.
