Question 1

What are the two types of drag?

Accepted Answer

Induced drag and parasite drag

Answer

Lift drag and thrust drag

Answer

Form drag and skin friction

Question 2

What is induced drag a byproduct of?

Accepted Answer

Creating lift

Answer

Air density

Answer

Speed

Question 3

Which of the following factors dictate induced drag?

Accepted Answer

Wing area, air density, speed, and angle of attack

Answer

Form drag and skin friction

Answer

Propeller pitch, thrust, and weight

Question 4

How can form drag be minimized?

Accepted Answer

Streamlining the aircraft

Answer

Increasing wing area

Answer

Polishing the aircraft

Question 5

What happens when the critical angle of attack is exceeded?

Accepted Answer

Lift decreases and induced drag increases

Answer

Thrust increases and weight decreases

Answer

Lift increases and drag decreases

Question 6

What is aerodynamic stalling?

Accepted Answer

A decrease in lift and an increase in drag at the critical angle of attack

Answer

A loss of air density

Answer

A sudden increase in thrust

Question 7

What conditions are assumed in the stalling speed quoted in the pilot operating handbook?

Accepted Answer

Idle power, level wings, and maximum allowable weight

Answer

High power, level wings, and minimum weight

Answer

Flaps down, high speed, and low altitude

Question 8

What is thrust?

Accepted Answer

The forward acting force on the aircraft

Answer

The downward acting force on the aircraft

Answer

The rearward acting force on the aircraft

Question 9

What does propeller pitch refer to?

Accepted Answer

How far the propeller travels in one revolution

Answer

The speed of the aircraft

Answer

The angle of attack of the wings

Question 10

When does fine pitch work best?

Accepted Answer

During takeoff and climb

Answer

Question 11

What is weight in the context of flight?

Accepted Answer

The downward acting force on the aircraft

Answer

The forward acting force on the aircraft

Answer

The rearward acting force on the aircraft

Question 12

What is the center of gravity?

Accepted Answer

The point where all weight forces are considered to act

Answer

The point where lift is maximized

Answer

The point where thrust is generated

Question 13

What does the maximum allowable gross takeoff weight include?

Accepted Answer

Airframe, fuel, people, and baggage

Answer
