between the 36th and 41th rows of seats. Aircraft can be divided into three parts: front, middle and rear. The wing of the Macau plane is between the 36th and 41th rows of seats, and the front seats are small in bump, low in noise, fast in getting on and off the plane, and fast in catering delivery. The wing is one of the important parts of an airplane. It is installed on the fuselage, and its main function is to generate lift. At the same time, an ammunition bin and an oil tank can be placed inside the wing, and the landing gear can be stored during flight. In addition, flaps to improve take-off and landing performance and ailerons for lateral control of the airplane are also installed on the wing, and some devices such as slats are installed at the leading edge of the wing to increase lift.
