Principles of Flight - ATPL - Airline Transport Pilot license

Test 10 domande Principles of Flight, tempo libero

1 - Differential aileron deflection: Equals the drag of the right and left aileron Is required to achieve the required roll-rate Increases the CLmax Is required to keep the total lift constant when ailerons are deflected

2 - The angle of attack of a blade section is the angle between the chord line and the: Induced airflow. Rotational airflow. Plane of rotation. Relative airflow.

3 - The terms 'q' and 'S' in the lift formula are: Dynamic pressure and the area of the wing Static pressure and dynamic pressure Static pressure and wing surface area Square root of surface and wing loading

4 - The angle of attack (aerodynamic angle of incidence) of an aerofoil is the angle between the: Chord line and the relative undisturbed airflow Bottom surface and the chord line Bottom surface and the relative airflow Bottom surface and the horizontal

5 - A CG location beyond the aft limit leads to: A too high pulling stick force during rotation in the take off An unacceptable low value of the manoeuvre stability (stick force per g, Fe/g) A better recovery performance in the spin An increasing static longitudinal stability

6 - Which of the following statements about the spin is correct? An aeroplane is prone to spin when the stall starts at the wing root In the spin, airspeed continuously increases During spin recovery the ailerons should be kept in the neutral position Every aeroplane should be designed such that it can never enter a spin

7 - What is the effect of an aft shift of the centre of gravity on ( 1) static longitudinal stability and( 2) the required control deflection for a given pitch change? (1) reduces (2) reduces (1) reduces (2) increases (1) increases (2) increases (1) increases (2) reduces

8 - What increases the stalling angle of attack ? Use of: Spoilers Flaps Fuselage mounted speed-brakes Slats

9 - Constant-speed propellers provide a better performance than fixed-pitch propellers because they: Produce a greater maximum thrust than a fixed-pitch propeller. Have a higher maximum efficiency than a fixed-pitch propeller. Have more blade surface area than a fixed-pitch propeller. Produce an almost maximum efficiency over a wider speed range.

10 - Trailing edge flap extension will: Increase the critical angle of attack and increase the value of CLmax Decrease the critical angle of attack and decrease the value of CLmax Decrease the critical angle of attack and increase the value of CLmax Increase the critical angle of attack and decrease the value of CLmax
