Question 1

The stall speed:

Accepted Answer

Increases with an increased weight

Answer

Decreases with an increased weight

Answer

Increases with the length of the wingspan

Answer

Does not depend on weight

Question 2

A jet transport aeroplane is in a straight climb at a constant IAS and constant weight. The operational limit that may be exceeded is:

Accepted Answer

MMO.

Answer

V

Answer

VMO.

Question 3

How are the speeds (shown in the figure) at point 1 and point 2 related to the relative wind / airflow V?

Accepted Answer

V1 = 0 and V2 > V

Answer

V1 > V2 and V2 < V

Answer

V1 = 0 and V2 = V

Answer

V1 < V2 and V2 < V

Question 4

The 'short period mode' is an:

Accepted Answer

Oscillation about the lateral axis

Answer

Unstable movement of the aeroplane, induced by the pilot

Answer

Oscillation about the longitudinal axis

Answer

Oscillation about the vertical axis

Question 5

Which statement is correct for a side slip condition at constant speed and side slip angle, where the geometric dihedral of an aeroplane is increased ?

Accepted Answer

The required lateral control force increases.

Answer

The required lateral control force does not change.

Answer

The required lateral control force decreases.

Answer

The stick force per g decreases.

Question 6

The effect of a ventral fin on the static stability of an aeroplane is as follows: (1=longitudinal, 2=lateral, 3=directional)

Accepted Answer

1: no effect, 2: negative, 3: positive

Answer

1: positive, 2: negative, 3: negative

Answer

1: negative, 2: positive, 3: positive

Answer

1: no effect, 2: positive, 3: negative

Question 7

The loss of total pressure in a shock wave is due to the fact that

Accepted Answer

Kinetic energy in the flow is converted into heat energy.

Answer

The speed reduction is too high.

Answer

The friction in the boundary layer is higher.

Answer

The static pressure decrease is comparatively high.

Question 8

When an aeroplane with the centre of gravity forward of the centre of pressure of the combined wing / fuselage is in straight and level flight, the vertical load on the tailplane will be:

Accepted Answer

Downwards.

Answer

Zero because in steady flight all loads are in equilibrium.

Answer

Upwards.

Answer

Downwards because it is always negative regardless of the position of the centre of gravity.

Question 9

A conventional stabiliser on a stable aeroplane in a normal cruise condition: 1 - always provides negative lift.2 - contributes to the total lift of the aeroplane.3 - may stall before the wing, in icing conditions, with large flap settings, unless adequate design and/or operational precautions are taken.4 - is necessary to balance the total pitch moment of the aeroplane. Which of the following lists all the correct statements ?

Accepted Answer

2, 3 and 4

Answer

1 and 4

Answer

1 and 3

Answer

1, 3 and 4

Question 10

Assuming an initial condition in straight and level flight with CL = 1. What will be the new value of CL after the value of the speed has doubled?

Accepted Answer

0.25

Answer

2.00

Answer

1.00

Answer

0.50
