1 - During initiation of a turn with speedbrakes extended, the roll spoiler function induces a spoiler deflection: Upward on the upgoing wing and downward on the downgoing wing. Downward on the upgoing wing and upward on the downgoing wing. On the downgoing wing only. On the upgoing wing only.

2 - The effects of very heavy rain (tropical rain) on the aerodynamic characteristics of an aeroplane are: Decrease of CLmax and decrease of drag Decrease of CLmax and increase of drag Increase of CLmax and decrease of drag Increase of CLmax and increase of drag

3 - Given two identical aeroplanes with wing mounted engines, one fitted with jet engines and the other with counter rotating propellers, what happens following an engine failure? The same yaw tendency for both aeroplanes regardless of left or right engine failure. The same roll tendency for both aeroplanes. More roll tendency for the propeller aeroplane. Less roll tendency for the propeller aeroplane.

4 - The Mean Aerodynamic Chord (MAC) for a given wing of any planform is The chord of a large rectangular wing The average chord of the actual aeroplane The chord of a rectangular wing with same moment and lift The wing area divided by the wing span

5 - What will increase the sensitivity to Dutch Roll? A forward movement of the centre of gravity. An increased static directional stability. An increased anhedral. An increased static lateral stability.

6 - The effect of the wing downwash on the static longitudinal stability of an aeroplane is: Negligible Positive Negative Smallest at high values of the lift coefficient

7 - Consider the steady flow through a stream tube where the velocity of the stream is V. An increase in temperature of the flow at a constant value of V will: Increase the mass flow Not affect the mass flow Decrease the mass flow Increase the mass flow when the tube is divergent in the direction of the flow

8 - An aeroplane has a stall speed of 100 KT at a load factor n = 1. In a turn with a load factor of n = 2, the stall speed is: 141 KT 200 KT 70 KT 282 KT

9 - Bernoulli's law states:(note: rho is the mean sea level density under ISA conditions Pstat is static pressure Pdyn is dynamic pressure Ptot is total pressure) Pstat + 1/2 rho V2 = constant

10 - Comparing the lift coefficient and drag coefficient at normal angle of attack: CL is much greater than CD CL is much lower than CD CL is lower than CD CL has approximately the same value as CD
