Question 1

The lift coefficient (CL) of an aeroplane in steady horizontal flight is 0.42. An increase in angle of attack of 1 degree increases CL by 0.1. A vertical up gust instantly changes the angle of attack by 3 degrees. The load factor will be:

Accepted Answer

1.71

Answer

0.74

Answer

2.49

Answer

1.49

Question 2

Which of the following statements about the spin is correct?

Accepted Answer

During spin recovery the ailerons should be kept in the neutral position

Answer

An aeroplane is prone to spin when the stall starts at the wing root

Answer

In the spin, airspeed continuously increases

Answer

Every aeroplane should be designed such that it can never enter a spin

Question 3

An aeroplane, being manually flown in the speed unstable region, experiences a disturbance that causes a speed reduction. If the altitude is maintained and thrust remains constant, the aeroplane speed will:

Accepted Answer

Further decrease.

Answer

Initially further decrease and thereafter increase.

Answer

Initially increase and thereafter decrease.

Answer

Increase.

Question 4

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 5

If flaps are deployed at constant IAS in straight and level flight, the magnitude of tip vortices will eventually: (flap span less than wing span)

Accepted Answer

Decrease

Answer

Increase

Answer

Increase or decrease, depending on the initial angle of attack

Answer

Remain the same

Question 6

If the sum of all the moments in flight is not zero, the aeroplane will rotate about the:

Accepted Answer

Centre of gravity.

Answer

Neutral point of the aeroplane.

Answer

Centre of pressure of the wing.

Answer

Aerodynamic centre of the wing.

Question 7

An aeroplane is provided with spoilers and in- and outboard ailerons. Roll control during cruise is provided by:

Accepted Answer

Inboard ailerons and roll-spoilers.

Answer

Outboard ailerons and roll-spoilers.

Answer

Inboard and outboard ailerons.

Answer

Outboard ailerons only.

Question 8

During landing of a low-winged jet aeroplane, the greatest elevator up deflection is normally required when the flaps are:

Accepted Answer

Fully down and the cg is fully forward.

Answer

Fully down and the cg is fully aft.

Answer

Up and the cg is fully forward.

Answer

Up and the cg is fully aft.

Question 9

Extension of FOWLER type trailing edge lift augmentation devices, will produce:

Accepted Answer

A nose-down pitching moment

Answer

A nose-up pitching moment

Answer

No pitching moment

Answer

A force which reduces drag

Question 10

VMO:

Accepted Answer

Should not be greater than VC

Answer

Is equal to the design speed for maximum gust intensity

Answer

Should be chosen in between VC and VD

Answer

Should not be less than VD
