Solved Accurately.
What is a monocoque fuselage structure? correct answers This is a structure without any
internal framework, where the skin carries all of the flight loads. 2-3
What is a semi-monocoque fuselage structure? correct answers This is a structure that has an
internal substructure attached to the aircrafts skin in order to increase the strength of the
fuselage. 2-4
What does the empennage consist of? correct answers Usually it consists of a vertical
stabilizer, the rudder, the vertical stabilizer, and the elevator. 2-5
What is a conventional landing gear? correct answers A landing gear with a rear-mounted
wheel, and the airplanes are sometimes referred to as tailwheel airplanes. 2-7
What type of landing gear does an airplane have if the third wheel is located on the nose of
the aircraft? correct answers A tricycle gear, or a nosewheel airplane. 2-7
What is the most common type of landing gear strut? correct answers An oleo strut, which
uses a piston enclosed in a cylinder with oil and compressed air to absorb the bumps and jolts
of landing and taxi operations. 2-9
What does the powerplant of the airplane include? correct answers The engine and the
propeller. 2-9
What are the primary and secondary purposes of the engine? correct answers The primary
purpose is to provide the power to turn the propeller. Engine mounted accessories provide the
secondary purposes of generating electrical power, creating a vacuum source for some flight
instruments, and to provide a source of heat for the pilot and passengers. 2-9
What is the purpose of a firewall? correct answers The firewall protects the occupants and
serves as a mounting point for the engine. 2-9
Where can aircraft operating limitations be found? correct answers In the approved flight
manual or pilots operating handbook, markings, placards, or a combination of these. 2-10
What is the purpose of trim devices? correct answers Trim helps minimize your workload by
aerodynamically helping you move a control surface, or maintain the surface in a desired
position. 2-6
What are the two main types of engines in use today? correct answers Reciprocating and
turbine. 2-14
What type of operating cycles do most reciprocating engines use? correct answers A four-
stroke operating cycle. 2-16
, What are the four cycles of the four-stroke operating cycle? correct answers 1. Intake: The
piston moves away from the cylinder head on the intake stroke, the intake valve opens and
the fuel/air mixture is drawn into the combustion chamber.
2. Compression: As the piston moves back toward the cylinder head, the intake valve closes
and the fuel/air mixture is compressed.
3. Power: When compression is almost complete, the spark plugs fire and the compressed
mixture is ignited to begin the power stroke. The expanding gases of the controlled burning
drive the piston, providing power that rotates the crankshaft.
4. Exhaust: The exhaust stroke expels the burned gases form the chamber through the opened
exhaust valve.
2-16
What is the purpose of the induction system of the engine? correct answers To bring outside
air into the engine, mix it with fuel in the proper proportion, and deliver it to the cylinders
where combustion occurs. 2-17
How do you control the induction system of the engine? correct answers With the throttle and
the mixture. The throttle controls engine speed by regulating the amount of fuel and air
mixture that flows into the cylinders, while the mixture controls the fuel/air ratio. 2-17
What does the carburetor in the engine do? correct answers It mixes the incoming air with
fuel and delivers it to the combustion chamber. 2-18
What is the operating principle of float-type carburetors? correct answers They are based on
the difference in pressure at the venture throat and the air inlet. 2-18
As an airplane climbs, do you enrich or lean the mixture to maintain optimum fuel/air ratio?
correct answers Lean. 2-19
What is happening when you lean the fuel/air mixture? correct answers You are decreasing
the fuel flow to compensate for decreased air density. This can also eliminate engine
roughness during runup at high elevation airports. 2-19
As altitude increases, what happens to air density? correct answers Air density decreases. 2-
19
If you are experiencing engine roughness during pre-takeoff runup at a high elevation airport,
or during climbs or cruise flight at high altitudes, what should you do? correct answers Lean
the fuel/air mixture in order to compensate for the less dense air, and full rich fuel. 2-19
What will happen if you do not adjust your mixture control during descents from high to low
altitudes? correct answers The mixture will become too lean, which may result in high engine
temperatures, which can cause engine wear and even engine failure over a long period of
time. 2-19
What is a disadvantage of float-type carburetors? correct answers Float-type carburetors are
susceptible to carburetor icing due to fuel vaporization and decreasing air pressure in the
venture. 2-19
