1. What are the two main methods of manufacturing aircraft?: Truss Construction and
Stressed Skin.
2. What are the two types of stressed skin construction?: Monocoque and Semi-Mono-
coque
3. What are the three main type of materials used on aircraft?: Ferrous, Non-ferrous and
Composite Materials
4. What are the three main structural assembles of a �xed wing aircraft?: Fuselage,
Wings and Empannage
5. What is the emmpannage?: the assembly of the tail surfaces that are used for control and stability
6. What 4 things does the empennage consist of?: Horizontal Stabiliser, Vertical Stabiliser,
Elevators and Rudder
7. What is the purpose of the Horizontal Stabiliser?: prevents the aircraft from pitching in �ight
8. What is the purpose of the vertical Stabiliser?: Prevents the aircraft from turning to port or
starboard in �ight.
9. What are the four main structural assemblies of a rotary wing aircraft?: Fuselage,
tailboom, landing Gear/skids and rotors.
10. What are the two types of landing gear on a helicopter?: Wheeled undercarriage and
xed skids.
11. What is the function of the main rotor?: to provide lift and the propelling force.
12. What is the function of the tail rotor?: To prevent the aircraft from rotating in the opposite
direction to its rotor.
13. What are the the helicopter control systems?: Collective pitch control, cyclic pitch control,
yaw control.

1. 1-1 AMA021
Which kind of stress is combination of compression
and tension?
A. Torsion
B. Shear
C. Bending: 1-1 Answer C.
Bending stress is a combination of compression and tension. For example, a rod has been shortened (compressed)
on the inside of the bend and stretched on the outside of the bend.
2. 1-2 AMA021
Longitudinal (fore and aft) structural members of a semi
monocoque fuselage are called
A. spars and ribs.
B. longerons and stringers.
C. spars and stringers.: 1-2 Answer B.
To overcome the strength/weight problem of monocoque
construction, a modi�cation called semi-monocoque
construction was developed. It also consists of frame
assemblies, bulkheads, and formers as used in the
monocoque design but, additionally, the skin is reinforced
by longitudinal members called longerons. Stringers are also used in the semimonocoque fuselage. These longitudinal
members are typically more numerous and lighter in weight than the longerons.
3. 1-3 AMA021
The monocoque fuselage relies largely on the strength of
A. bulkheads and longerons
B. longerons and formers
C. skin or covering: 1-3 Answer C.
