（2）wing / airfoil The wings generate most of the lift necessary for flight. ① aileron Ailerons are parts of the wing which are used to roll the aircraft. At the trailing edge, it’s an aileron. ②leading edge slat ③trailing edge flap Flaps and slats are parts of the wing which are used during take off and landing to increase lift and drag. ④spoiler Spoilers are parts of the wing which are used to roll the aircraft and to decrease lift and increase drag during landings. 21 Between the leading and trailing edges, it’s a spoiler.

7. An airplane can be divided into the following groups according to the positions of the wing relative to the fuselage. （1）low wing airplane A low wing airplane is an airplane whose wing is below the cabin. （2） mid wing airplane A mid wing airplane is an airplane whose wing is anywhere between the fuselage. （3）high wing airplane A high wing airplane is an airplane whose wing is above the cabin.

（4）landing gear / undercarriage Airplane require landing gear for taxiing, takeoff and landing. （5）powerplant Most modern aircraft are powered by gas turbine, or jet engines.
（3）empennage / the tail assembly ① vertical stabilizer ②rudder A rudder is a control surface connected to the vertical stabilizer and is used to yaw the aircraft. ③ horizontal stabilizer ④ elevator Elevators are control surfaces connected to the horizontal stabilizer and are used to pitch the aircraft. ⑤stabilator Stabilators are control surfaces which provide both horizontal stability and pitch control for the aircraft.

8. An airplane can be divided into the following groups according to its mission. （1）military aircraft （2）civil airct’s Structure
6. An airplane can be divided into the following groups according to the number of wings. （1）monoplane A monoplane is an airplane with a single pair of wings. （2） biplane A biplane is an old-fashioned type of airplane with two pairs of wings, one above the other. （3）multiplane A multiplane is an airplane with more than two pairs 15 of wings, say, three or four pairs.

5. An airplane can be divided into the following groups according to the type of landing gear. （1）landplane A landplane is an airplane that can take off from or land on land. （2）seaplane / hydroplane A seaplane or hydroplane is a type of airplane that can take off from or land on water. （3）amphibian An amphibian is an airplane which can land on both 14 land and water.
