Question 1

When Fowler type trailing edge flaps are extended at a constant angle of attack, the following changes will occur:

Accepted Answer

CL and CD increase

Answer

CL increases and the centre of pressure moves forward

Answer

CD decreases and the centre of pressure moves aft

Answer

CL increases and CD remains constant

Question 2

The angle of attack of a blade section is the angle between the chord line and the:

Accepted Answer

Relative airflow.

Answer

Induced airflow.

Answer

Rotational airflow.

Answer

Plane of rotation.

Question 3

Dihedral of the wing:

Accepted Answer

Increases the static lateral stability.

Answer

Is only positive for aeroplanes with high mounted wings.

Answer

Is the only way to increase the static lateral stability.

Answer

Decreases the static lateral stability.

Question 4

Interference drag is the result of:

Accepted Answer

Aerodynamic interaction between aeroplane parts (for example, wing / fuselage)

Answer

Separation of the induced vortex

Answer

Downwash behind the wing

Answer

The addition of induced and parasite drag

Question 5

VLE is defined as the:

Accepted Answer

Maximum landing gear extended speed.

Answer

Maximum flap extended speed.

Answer

Maximum speed at which the landing gear may be extended or retracted.

Answer

Maximum authorised speed.

Question 6

The difference between IAS and TAS will:

Accepted Answer

Decrease with decreasing altitude

Answer

Increase with decreasing temperature

Answer

Increase with increasing air density

Answer

Decrease with increasing speed

Question 7

One method to compensate adverse yaw is:

Accepted Answer

A differential aileron.

Answer

A balance panel.

Answer

An anti-balance tab.

Answer

A balance tab.

Question 8

Dihedral of the wing is:

Accepted Answer

The angle between the 0.25 chord line of the wing and the lateral axis

Answer

The angle between the leading edge of the wing and the lateral axis

Answer

The angle between the 0.25 chord line of the wing and the vertical axis

Answer

The angle between the 0.25 chord line of the wing and the horizon

Question 9

In general transport aeroplanes with power assisted flight controls are fitted with an adjustable stabilizer instead of trim tabs on the elevator. This is because:

Accepted Answer

Effectiveness of trim tabs is insufficient for those aeroplanes

Answer

The pilot does not feel the stick forces at all

Answer

Trim tab deflection increases Mcrit

Answer

Mechanical adjustment of trim tabs creates too many problems

Question 10

The trailing edge flaps when extended:

Accepted Answer

Degrade the best angle of glide

Answer

Significantly lower the drag

Answer

Significantly increase the angle of attack for maximum lift

Answer

Increase the zero lift angle of attack
