CORRECT Answers
What are the three axes of an aircraft and name the associated emotions related to each. -
CORRECT ANSWER- ✔✔Pitching, which is lateral axis, rolling which is longitudical axis,
and yawing which is vertical axis
Name the four forces that act upon an aircraft in relation to straight and level, unaccelerated
flight. - CORRECT ANSWER- ✔✔Thrust, lift, weight, and drag
Explain C.G (Center of Gravity) - CORRECT ANSWER- ✔✔The specific point where the
mass or weight of an aircraft may be set to center. That is, a point around which, if the aircraft
could be suspended or balanced, the aircraft would remain level.
Drag opposes _____, weight opposes ______. - CORRECT ANSWER- ✔✔Thrust, lift
The position of the _____ determines the stability of an aircraft in flight. - CORRECT
ANSWER- ✔✔Center of gravity
List the five major components of an aircraft. - CORRECT ANSWER- ✔✔Fuselage, wings,
empennage, landing gear, power plant.
What are the two control surfaces that are attached to the trailing edge of the wings and
explain the function of each. - CORRECT ANSWER- ✔✔Ailerons: at the midpoint of each
wing, they move in opposite directions to create forces that produce roll.
Flaps: flush with the wing, increases lifting force.
Name the five components of an empennage. - CORRECT ANSWER- ✔✔Horizontal
stabilizer, vertical stabilizer, rudder, trim tabs, elevator.
,What part of the aircraft covers the engine and what is its purpose? - CORRECT ANSWER-
✔✔The cowling covers the engine, and streamlines the flow of air around the engine to help
cool the engine by conducting air around the cylinders.
What is the difference between a tricycle gear aircraft and a conventional gear aircraft. -
CORRECT ANSWER- ✔✔The tricycle gear has a wheel in the front, the conventional gear
has the wheel in the back.
How are most aircraft steered? - CORRECT ANSWER- ✔✔Most aircraft or steered by
moving the rudder pedals.
Which primary flight control controls pitch? - CORRECT ANSWER- ✔✔The elevator
primarily controls flight pitch.
The primary flight control which controls roll is ______ - CORRECT ANSWER-
✔✔Ailerons
Yaw is controlled by use of a ______ - CORRECT ANSWER- ✔✔Rudder
There are many different types of flaps, give 4 examples - CORRECT ANSWER- ✔✔Slotted
flap, basic section, plain flap, split flap, fowler flap, slotted fowler flap
What are the three categories of instrumentation? - CORRECT ANSWER- ✔✔Control,
performance, navigation instruments.
Where are the PFD and MFD located in the aircraft? - CORRECT ANSWER- ✔✔In the
dashboard
Explain semimonocoque construction. - CORRECT ANSWER- ✔✔The semimonocoque
construction reinforces the stressed skin by taking some of the bending stress from the main
section of the fuselage, also includes a firewall.
,What is a major advantage of using composite materials in an aircraft? - CORRECT
ANSWER- ✔✔Composite materials has a lighter weight, it is also very smooth, compound,
and curved as well as aerodynamic. It also does not corrode, and it is flexible.
What is a major disadvantage of using composite construction? - CORRECT ANSWER-
✔✔Composite construction is very fragile.

plane, which is a theoretical level where the weight of the atmosphere is 29.92 HG.
What is density altitude? - CORRECT ANSWER- ✔✔The vertical distance above sea level
in the standard atmosphere at which a given density is to be found. Also it is pressure altitude
converted for non-standard temperature.

ANSWER- ✔✔59, 15, 29.92, 1,013.2
What is the standard temperature lapse rate? - CORRECT ANSWER- ✔✔The lapse rate is
one in which the temperature decreases at a rate of 3.5 degrees Fahrenheit or 2°C for
thousand feet up to 36,000 feet. Which is approximately -65°F or -55°C.
What is the standard pressure lapse rate? - CORRECT ANSWER- ✔✔The pressure decreases

A decrease in air density means a _______ density altitude, while an increase in air density
means a ______ density altitude - CORRECT ANSWER- ✔✔Increased, decreased
What type of effect does high density altitude have on aircraft performance? - CORRECT
ANSWER- ✔✔High density altitude has lower performance and efficiency.
, Define mean camber line - CORRECT ANSWER- ✔✔The mean camber line is equidistant at
all points
Explain angle of attack. - CORRECT ANSWER- ✔✔The angle of attack is defined as the
angle formed by the wing chord line and the relative wind.
Explain how newtons third law applies to an airplane - CORRECT ANSWER- ✔✔The
propeller pushes the air to the plane which is the action, the opposite reaction is the plane
going forward.
Which principle states that as the velocity of a moving fluid increases, the pressure with the
fluid decreases? - CORRECT ANSWER- ✔✔Bernoulli's Principle of Differential Pressure
According to Bernoulli's Principle of Differential Pressure, The increase of speed of the air
