1 - Which kinds of drag contribute to total drag? Form drag, skin-friction drag, interference drag Interference drag and parasite drag Induced drag, form drag, skin-friction drag Induced drag and parasite drag

2 - What effects typically result from propeller icing? Reduced power output, decreasing RPM Increased power output, decreasing RPM. Increased power output, increasing RPM. Reduced power output, increasing RPM.

3 - How does a laminar boundary layer differ from a turbulent boundary layer? The laminar boundary layer produces lift, the turbulent boundary layer produces drag The turbulent boundary layer is thicker and provides less skin-friction drag The laminar boundary layer is thinner and provides more skin-friction drag The turbulent boundary layer can follow the airfoil camber at higher angles of attack

4 - In case of a stall it is important to... Increase the bank angle and reduce the speed Increase the angle of attack and increase the speed. Decrease the angle of attack and increase the speed Increase the angle of attack and reduce the speed.

5 - In order to improve the stall characteristics of an aircraft, the wing is twisted outwards (the angle of incidence varies spanwise). This is known as... Aerodynamic washout Arrow shape V-form. Geometric washout

6 - Point number 5 in the figure indicates which flight state? See figure (PFA-008) (1,00 P.) Siehe Anlage 5

question 51-95-96.jpg

Best gliding angle Slow flight Stall Inverted flight

7 - What leads to a decreased stall speed Vs (IAS)? Lower altitude Lower density Higher load factor Decreasing weight

8 - The laminar boundary layer on the aerofoil is located between... The transition point and the separation point. The stagnation point and the transition point. The transition point and the center of pressure The stagnation point and the center of pressure

9 - A take-off with flaps in take-off position causes... An increased rate of climb An increased acceleration A shortening of the take-off run. A decrease in drag.

10 - Which statement about the airflow around an aerofoil is correct if the angle of attack decreases? The center of pressure moves aft The stagnation point remains constant The stagnation point moves down The center of pressure moves forward
