Question 1

High Aspect Ratio, as compared with low Aspect Ratio, has the effect of:

Accepted Answer

Decreasing induced drag and critical angle of attack

Answer

Increasing lift and critical angle of attack

Answer

Increasing lift and drag

Answer

Increasing induced drag and decreasing critical angle of attack

Question 2

Entering the stall the centre of pressure of a straight (1) wing and of a strongly swept back wing (2) will:

Accepted Answer

(1) move aft, (2) move forward

Answer

(1) not move (2) move forward

Answer

(1) move aft, (2) move aft

Answer

(1) move aft, (2) not move

Question 3

Induced drag at constant IAS is affected by:

Accepted Answer

Aeroplane weight

Answer

Aeroplane wing location

Answer

Engine thrust

Answer

Angle between wing chord and fuselage centre line

Question 4

Which statement about a primary control surface controlled by a servo tab, is correct?

Accepted Answer

The position is undetermined during taxiing, in particular with tailwind

Answer

Due to the effectiveness of the servo tab the control surface area can be smaller

Answer

The control effectiveness of the primary surface is increased by servo tab deflection

Answer

The servo tab can also be used as a balance tab

Question 5

To increase the critical Mach number a conventional aerofoil should

Accepted Answer

Have a low thickness to chord ratio.

Answer

Be used with a high angle of attack.

Answer

Have a large camber.

Answer

Have a large leading edge radius.

Question 6

The angle of attack (aerodynamic angle of incidence) of an aerofoil is the angle between the:

Accepted Answer

Chord line and the relative undisturbed airflow

Answer

Bottom surface and the chord line

Answer

Bottom surface and the relative airflow

Answer

Bottom surface and the horizontal

Question 7

The lift coefficient (CL) of an aeroplane in steady horizontal flight is 0.35. An increase in angle of attack of 1 degree would increase CL by 0.079. If a vertical gust instantly changes the angle of attack by 2 degrees, the load factor will be:

Accepted Answer

1.45

Answer

0.9

Answer

1.9

Answer

0.45

Question 8

Given an initial condition in straight and level flight with a speed of 1.4 VS. The maximum bank angle attainable without stalling in a steady co-ordinated turn, whilst maintaining speed and altitude, is approximately:

Accepted Answer

60°

Answer

30°

Answer

32°

Answer

44°

Question 9

What is the SI unit of measurement for power?

Accepted Answer

Nm/s

Answer

Pa/m2

Answer

Kgm/s2

Answer

N/m

Question 10

The angle of attack of a two dimensional wing section is the angle between:

Accepted Answer

The chord line of the aerofoil and the free stream direction

Answer

The chord line of the aerofoil and the fuselage centreline

Answer

The chord line and the camber line of the aerofoil

Answer

The fuselage centreline and the free stream direction
