Accepted Answer

Angle of incidence

Answer

Climb path angle

Answer

Angle of attack

Answer

Glide path angle

Question 2

Assuming ISA conditions, which statement with respect to the climb is correct ?

Accepted Answer

At constant IAS the Mach number increases

Answer

At constant Mach number the IAS increases

Answer

At constant IAS the TAS decreases

Answer

At constant TAS the Mach number decreases

Question 3

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 4

An aeroplane has a stall speed of 100 KT at a load factor n = 1. In a turn with a load factor of n = 2, the stall speed is:

Accepted Answer

141 KT

Answer

200 KT

Answer

70 KT

Answer

282 KT

Question 5

In which situation would the wing lift of an aeroplane in straight and level flight have the highest value?

Accepted Answer

Forward centre of gravity and idle thrust

Answer

Forward centre of gravity and take-off thrust

Answer

Aft centre of gravity and idle thrust

Answer

Aft centre of gravity and take-off thrust

Question 6

Positive static longitudinal stability means that a:

Accepted Answer

Nose-down moment occurs after encountering an up-gust.

Answer

Nose-up moment occurs with a speed change at constant angle of attack.

Answer

Nose-up moment occurs after encountering an up-gust.

Answer

Nose-down moment occurs with a speed change at constant angle of attack.

Question 7

What data may be obtained from the Buffet Onset Boundary chart?

Accepted Answer

The values of the Mach Number at which low speed and Mach Buffet occur at different weights and altitudes

Answer

The values of Mcrit at different weights and altitudes

Answer

The values of MMO at different weights and altitudes

Answer

The values of the Mach Number at which low speed and shock-stall occur at different weights and altitudes

Question 8

In a twin engine jet aeroplane (engines mounted below the low wings) the thrust is suddenly increased. Which elevator deflection will be required to maintain the pitching moment zero ?

Accepted Answer

Down.

Answer

Up.

Answer

It depends on the position of the centre of gravity.

Answer

No elevator movement will required because the thrust line of the engines remains unchanged.

Question 9

The application of the area rule on aeroplane design will decrease the

Accepted Answer

Wave drag.

Answer

Form drag.

Answer

Induced drag.

Answer

Skin friction drag.

Question 10

Induced drag may be reduced by:

Accepted Answer

An increase in aspect ratio

Answer

An increase in the taper ratio of the wing

Answer

A decrease of the aspect ratio

Answer

The use of a wing tip with a much thinner aerofoil
