POKERDEX The A321neo is a narrow-body (single aisle) aircraft with a retractable tricycle landing gear, powered by two wing pylon-mounted turbofan engines. It is a low-wing cantilever monoplane with a conventional tail unit having a single vertical stabiliser and rudder. Initial A321neos have the A321ceo exit door configuration with four exit door pairs until the Airbus Cabin-Flex (ACF) layout can be selected. Changes from the A321ceo includes a new engine and extended fuselage fuel tanks. By permanently replacing the second door pair in front of the wing (R2/L2) with a new second pair of overwing exits, the capacity of the A321neo is increased from 220 seats to 240 seats and fuel efficiency per seat is increased by 6%, exceeding 20% together with the new engines and the sharklets. The third door pair (R3/L3), aft of the wings, is moved aft four frames back and could be plugged for 200 seats or less, and one overwing exit can be plugged for 165 seats or less.|How does all of this Come Together?
