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 - "Longitudinal stability" is referred to as stability around which axis? Propeller axis Vertical axis Longitudinal axis Lateral axis

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 - 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

4 - Which design feature can compensate for adverse yaw? Wing dihedral Full deflection of the aileron Aileron trim Differential aileron defletion

5 - 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.

6 - Stabilization around the lateral axis during cruise is achieved by the... Horizontal stabilizer. Airlerons Wing flaps. Vertical rudder.

7 - Which statement about induced drag during the horizontal cruise flight is correct? Induced drag has a minimum at a certain speed and increases at higher as well as lower speeds Induced drag has a maximum at a certain speed and decreases at higher as well as lower speeds Induced drag increases with increasing airspeed Induced drag decreases with increasing airspeed

8 - Which option states a benefit of wing washout? Structurally the wing is made more rigid against rotation With the washout the form drag reduces at high speeds Greater hardness because the wing can withstand more torsion forces At high angles of attack the effectiveness of the aileron is retained as long as possible

9 - How do lift and drag change when approaching a stall condition? Lift and drag decrease Lift and drag increase Lift decreases and drag increases Lift increases and drag decreases

10 - The elevator deflection during take-off rotation... Is increased for a front centre of gravity. Is increased for a rear centre of gravity Is increased at high speeds. Is independent of the speed.
