SPC Student Pilot Basic Aerodynamics 2

Question 1

Which aerodynamic force acts perpendicular to the relative wind?

Accepted Answer

Lift

Answer

Drag

Answer

Thrust

Answer

Weight

Question 2

What happens to induced drag as airspeed increases?

Accepted Answer

It decreases

Answer

It increases proportionally

Answer

It remains constant

Answer

It doubles with each knot

Question 3

The chord line of a wing is defined as:

Accepted Answer

An imaginary line from the leading edge to the trailing edge

Answer

The curved upper surface of the wing

Answer

The angle between the wing and the horizon

Answer

The distance from wingtip to wingtip

Question 4

What term describes the angle between the chord line and the relative wind?

Accepted Answer

Angle of attack

Answer

Dihedral angle

Answer

Angle of incidence

Answer

Sweepback angle

Question 5

During a coordinated level turn, total lift must be greater than weight because:

Accepted Answer

Only the vertical component of lift supports the aircraft's weight

Answer

Bank angle reduces the effectiveness of the rudder

Answer

The horizontal component of lift causes the aircraft to climb

Answer

Increased speed reduces lift efficiency

Question 6

What is the primary cause of parasite drag?

Accepted Answer

Interference between airflow and aircraft structure/skin friction

Answer

Generation of lift by the wings

Answer

Wing vortices trailing from the wingtips

Answer

Changes in angle of attack

Question 7

What is the stagnation point on an airfoil?

Accepted Answer

The point where airflow velocity is zero and pressure is highest

Answer

The point of maximum thickness

Answer

The point where turbulent flow begins

Answer

The trailing edge where airflow rejoins
