Question 1

What is done when a force acts upon a body and moves it?

Answer 1

Work (work equals Force times Distance)

Question 2

Which of Newton’s Laws state that “a body at rest tends to remain at rest and a body in motion tends
to remain in motion … unless acted upon by some unbalanced force?”

Answer 2

Newton’s first law of equilibrium

Question 3

What is the measurement of the average kinetic energy of air particles called?

Answer 3

Temperature

Question 4

True or false. Dynamic pressure is the measurement of force that molecules exert on each other in a still fluid.

Answer 4

False, that is the definition of static pressure

Question 5

If the right side of cross-sectional area of a streamtube is decreased the velocity of the mass flow at that point will what?

Answer 5

Increase

Question 6

A higher than standard day density altitude will cause the takeoff roll to be what?

Answer 6

Longer, due to decrease in performance

Question 7

True or false. Groundspeed is indicated airspeed corrected for winds.

Answer 7

False, ground speed is true airspeed corrected for winds

Question 8

What happens t true Airspeed (TAS) as you climb in altitude for a constant indicated airspeed (IAS)?

Answer 8

TAS increases

Question 9

The apparent motion of the air with respect to the motion of the aircraft is defined as?

Answer 9

The relative wind. Relative wind is opposite flight path

Question 10

The angle of attack (AOA) is defined as what?

Answer 10

The angle between the relative wind and the chordline of the airfoil

Question 11

What is a benefit of a tapered wing?

Answer 11

Structural stiffness

Question 12

Which aircraft would have a higher aspect ratio?

a. Glider
b. Fighter aircraft
c. Bomber aircraft
d. Balloon

Answer 12

Glider

Question 13

Having a CG that is too far aft causes the aircraft to exhibit what behavior?

Answer 13

A tendency to pitch up into a stall

Question 14

What is the name of the point from which movements in roll, yaw, and pitch axes are measured.

Answer 14

Center of gravity

Question 15

The axis about which the airplane’s nose moves up and down is called what?

Answer 15

The lateral or pitch axis

Question 16

How is moment created?

Answer 16

Moment is created when a force is applied at some distance from an axis or fulcrum, producing rotation about that point

Question 17

Mass per unit of volume defines what?

Answer 17

Density

Question 18

What is potential energy?

Answer 18

The ability of a body to do work due to its position or state of being

Question 19

The Law of Interaction states what?

Answer 19

“For every action there is an equal and opposite reaction.”

Question 20

What will happen to true airspeed compared to indicated airspeed at 10,000 feet altitude?

Answer 20

It will be greater than the indicated airspeed due to the lower density

Question 21

What is the chord of an airfoil is defined as?

Answer 21

A measure of the wing along the chordline, from the leading edge to the trailing edge

Question 22

What happens to air density at 10,000 feet compared to at 5000 feet.

Answer 22

Lower

Question 23

What does mass/volume represent?

Answer 23

Density

Question 24

What is the altimeter setting for standard day where pressure altitude equals true altitude?

Answer 24

29.92/1013

Question 25

What is the name of the point at which all weight is concentrated?

Answer 25

Center of gravity

Question 26

Which axis controls the aircraft nose moves left or right about the center of gravity?

Answer 26

Yaw axis
