Question 1

What describes "wing loading"?

Accepted Answer

Weight per wing area

Answer

Drag per wing area

Answer

Drag per weight

Answer

Wing area per weight

Question 2

What structural item provides lateral stability to an airplane?

Accepted Answer

Wing dihedral

Answer

Differential aileron deflection

Answer

Vertical tail

Answer

Elevator

Question 3

What pattern can be found at the stagnation point?

Accepted Answer

Streamlines are divided into airflow above and below the profile

Answer

The boundary layer starts separating on the upper surface of the profile

Answer

The laminar boundary layer changes into a turbulent boundary layer

Answer

All aerodynamic forces can be considered as attacking at this single point

Question 4

Where is interference drag generated?

Accepted Answer

At the wing root

Answer

At the ailerons

Answer

At the the gear

Answer

Near the wing tips

Question 5

The aerodynamic rudder balance...

Accepted Answer

Reduces the control stick forces

Answer

Improves the rudder effectiveness.

Answer

Reduces the control surfaces

Answer

Delays the stall.

Question 6

What kind of drag is NOT part of the parasite drag?

Accepted Answer

Induced drag

Answer

Interference drag

Answer

Skin-friction drag

Answer

Form drag

Question 7

What has to be considered with regard to the center of gravity position?

Accepted Answer

Only correct loading can assure a correct and safe center of gravity position

Answer

The center of gravity's position can only be determined during flight.

Answer

By moving the elevator trim tab, the center of gravity can be shifted into a correct position

Answer

By moving the aileron trim tab, the center of gravity can be shifted into a correct position.

Question 8

The angle (alpha) shown in the figure is referred to as... See figure (PFA-003) DoF: direction of airflow (1,00 P.) Siehe Anlage 3

Accepted Answer

Angle of attack.

Answer

Lift angle.

Answer

Angle of incidence

Answer

Angle of inclination

Question 9

The right aileron deflects upwards, the left downwards. How does the aircraft react?

Accepted Answer

Rolling to the right, yawing to the left

Answer

Rolling to the left, no yawing

Answer

Rolling to the right, yawing to the right

Answer

Rolling to the left, yawing to the right

Question 10

"Longitudinal stability" is referred to as stability around which axis?

Accepted Answer

Lateral axis

Answer

Propeller axis

Answer

Vertical axis

Answer

Longitudinal axis
