Question 1

The unit of measurement of pressure is:

Accepted Answer

Psi

Answer

Kg/dm2

Answer

Lb/gal

Answer

Kg/m3

Question 2

'Tuck under' is:

Accepted Answer

The tendency to nose down when speed is increased into the transonic flight regime.

Answer

The tendency to nose down when the control column is pulled back.

Answer

Shaking of the control column at high Mach Number.

Answer

The tendency to nose up when speed is increased into the transonic flight regime.

Question 3

On a swept wing aeroplane at low airspeed, the 'pitch up' phenomenon:

Accepted Answer

Is caused by wingtip stall

Answer

Is caused by boundary layer fences mounted on the wings

Answer

Is caused by extension of trailing edge lift augmentation devices

Answer

Never occurs, since a swept wing is a 'remedy' to pitch up

Question 4

Two identical aircraft A and B, with the same mass, are flying steady level co-ordinated 20 degree bank turns. If the TAS of A is 130 KT and that of B is 200 KT:

Accepted Answer

The rate of turn of A is greater than that of B

Answer

The lift coefficient of A is less than that of B

Answer

The turn radius of A is greater than that of B

Answer

The load factor of A is greater than that of B

Question 5

Vortex generators on the upper side of the wing surface will:

Accepted Answer

Decrease the intensity of shock wave induced air separation.

Answer

Increase the critical Mach Number.

Answer

Decrease the span wise flow at high Mach Numbers.

Answer

Increase the magnitude of the shock wave.

Question 6

The span-wise flow is caused by the difference between the air pressure on top and beneath the wing and its direction of movement goes from:

Accepted Answer

Beneath to the top of the wing via the wing tip

Answer

The top to beneath the wing via the leading edge

Answer

Beneath to the top of the wing via the trailing edge

Answer

The top to beneath the wing via the wing's trailing edge

Question 7

Winglets

Accepted Answer

Decrease the induced drag

Answer

Decrease the static lateral stability

Answer

Increase the manoeuvrability

Answer

Create an elliptical lift distribution

Question 8

Which load factor determines VA?

Accepted Answer

Manoeuvring limit load factor.

Answer

Manoeuvring flap limit load factor.

Answer

Gust load factor at 66 ft/sec gust.

Answer

Manoeuvring ultimate load factor.

Question 9

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?

Accepted Answer

(1) reduces (2) reduces

Answer

(1) reduces (2) increases

Answer

(1) increases (2) increases

Answer

(1) increases (2) reduces

Question 10

With increasing altitude and constant IAS the static lateral stability ( 1) and the dynamic lateral/directional stability ( 2) of an aeroplane with swept-back wing will:

Accepted Answer

(1) increase (2) decrease

Answer

(1) increase (2) increase

Answer

(1) decrease (2) increase

Answer

(1) decrease (2) decrease
