Principle of Flight - PPL(A) English - Private Pilot License (Aircraft)

Test 10 domande PPL(A) English - Private Pilot License (Aircraft) - Principle of Flight, tempo libero

1 - Pressure compensation on an wing occurs at the... Wing roots Wing tips. Trailing edge Leading edge.

2 - Which parts of an aircraft mainly affect the generation of induced drag? The front part of the fuselage. The wing tips The lower part of the gear. The outer part of the ailerons

3 - What structural item provides directional stability to an airplane? Differential aileron deflection Large vertical tail Wing dihedral Large elevator

4 - Which constructive feature is shown in the figure? See figure (PFA-006) L: Lift (1,00 P.) Siehe Anlage 4

Longitudinal stability by wing dihedral Lateral stability by wing dihedral Differential aileron deflection Directional stability by lift generation

5 - How is the balance of forces affected during a turn? Lift force must be increased to compensate for the sum of centrifugal and gravitational force The net force results from superposition of gravity and centripetal forces The horizontal component of the lift force during a turn is the centrifugal force A lower lift force compensates for a lower net force as compared to level flight

6 - 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

7 - The change in pitch at a propeller blade from the root to the tip ensures... That the most thrust is produced at the blade tip That the most thrust is produced at the blade root A nearly constant load by a constant effective angle of attack over the entire length of the blade. The largest possible angle of attack at the blade tip

8 - Number 3 in the drawing corresponds to the... See figure (PFA-010) (1,00 P.) Siehe Anlage 1

Chord Thickness Camber line Chord line.

9 - 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.

10 - Which statement about lift and angle of attack is correct? Too large angles of attack can lead to an exponential increase in lift Increasing the angle of attack results in less lift being generated by the aerofoil Increasing the angle of attack too far may result in a loss of lift and an airflow separation Decreasing the angle of attack results in more drag being generated by the aerofoil
