Principles of Flight - ATPL - Airline Transport Pilot license

Test 10 domande ATPL - Airline Transport Pilot license - Principles of Flight, tempo libero

1 - Some aeroplanes have a 'waist' or 'coke bottle' contoured fuselage. This is done to Increase the strength of the wing root junction. Apply area rule. Improve the low speed characteristics. Fit the engine intakes better to the fuselage.

2 - An aeroplane is descending at a constant Mach number from FL 350. What is the effect on true airspeed ? It decreases as pressure increases It increases as temperature increases It remains constant It decreases as altitude decreases

3 - Which aeroplane design has the highest probability of a super stall? A canard wing Swept wings A T-tail A low horizontal tail

4 - Which of the following statements is true? Flight in severe turbulence may lead to a stall and/or structural limitations being exceeded Flap extension in severe turbulence at constant speed moves the centre of pressure aft, which increases the structural limitation margins By increasing the flap setting in severe turbulence at constant speed the stall speed will be reduced and the risk for exceeding the structural limits will be decreased Flap extension in severe turbulence at constant speed increases both the stall speed and the structural limitation margins

5 - Which statement about induced drag and tip vortices is correct? Tip vortices can be diminished by vortex generators The flow direction at the upper side of the wing has a component in wing root direction, the flow at the underside of the wing in wing tip direction The wing tip vortices and the induced drag decrease at increasing angle of attack The flow direction at the upper and under side of the wing, both deviate in wing tip direction

6 - Examples of aerodynamic balancing of control surfaces are: Upper and lower rudder, seal between wing's trailing edge and leading edge of a control surface Seal between wing's trailing edge and leading edge of a control surface, horn balance Fowler flaps, upper and lower rudder Weight in the nose of the control surface, horn balance

7 - The lift of an aeroplane of weight W in a constant linear climb with a climb angle (gamma) is approximately: W (1-tan.gamma) W (1-sin.gamma) W / cos.gamma W cos.gamma

8 - A boundary layer fence on a swept wing will: Improve the high speed characteristics Improve the low speed characteristics Improve the lift coefficient of the trailing edge flap Increase the critical Mach Number

9 - Tick force per g is independent of altitude.II Stick force per g increases when the centre of gravity moves forward. I is correct, II is correct. I is correct, II is incorrect. I is incorrect, II is correct. I is incorrect, II is incorrect

10 - If you decrease the propeller pitch during a glide with idle-power at constant IAS the lift to drag ratio will: Increase and the rate of descent will increase Decrease and the rate of descent will decrease Decrease and the rate of descent will increase Increase and the rate of descent will decrease
