Question 1

Positive static lateral stability is the tendency of an aeroplane to:

Accepted Answer

Roll to the left in the case of a positive sideslip angle (aeroplane nose to the left).

Answer

Roll to the right in the case of a positive sideslip angle (aeroplane nose to the left).

Answer

Roll to the right in a right turn.

Answer

Roll to the left in a right turn.

Question 2

Which of the following statements about a Mach trimmer is correct?

Accepted Answer

A Mach trimmer corrects the change in stick force stability of a swept wing aeroplane above a certain Mach number

Answer

A straight wing aeroplane always needs a Mach trimmer for flying at Mach numbers close to MMO

Answer

The Mach trimmer corrects the natural tendency of a swept wing aeroplane to pitch-up

Answer

A Mach trimmer reduces the stick force stability of a straight wing aeroplane to zero at high Mach numbers

Question 3

Which combination of speeds is applicable for structural strength in gust (clean configuration)?

Accepted Answer

50 ft/sec and VC

Answer

55 ft/sec and VB

Answer

65 ft/sec at all speeds

Answer

66 ft/sec and VD

Question 4

A slotted flap will increase the CLmax by:

Accepted Answer

Increasing the camber of the aerofoil and re-energising the airflow

Answer

Decreasing the skin friction

Answer

Increasing the critical angle of attack

Answer

Increasing only the camber of the aerofoil

Question 5

During the retraction of the flaps at a constant angle of attack the aeroplane starts to (all other factors of importance being constant):

Accepted Answer

Sink suddenly

Answer

Climb

Answer

Bank

Answer

Yaw

Question 6

Which of the following statements about stall speed is correct?

Accepted Answer

Decreasing the angle of sweep of the wing will decrease the stall speed

Answer

Use of a T-tail will decrease the stall speed

Answer

Increasing the angle of sweep of the wing will decrease the stall speed

Answer

Increasing the anhedral of the wing will decrease the stall speed

Question 7

What is the approximate value of the lift of an aeroplane at a gross weight of 50000 N, in a horizontal coordinated 45 degrees banked turn?

Accepted Answer

70000 N

Answer

60000 N

Answer

50000 N

Answer

80000 N

Question 8

In order to maintain straight and level flight at a constant airspeed, whilst the flaps are being retracted, the angle of attack must be:

Accepted Answer

Increased

Answer

Held constant

Answer

Decreased

Answer

Increased or decreased depending upon the type of flap

Question 9

If the nose of an aeroplane yaws left, this causes:

Accepted Answer

A roll to the left.

Answer

A decrease in relative airspeed on the right wing.

Answer

An increase in lift on the left wing.

Answer

A roll to the right.

Question 10

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
