1

The effect of hoar frost forming on the wings of an aeroplane is -

Hazardous, because it can substantially increase stalling speed 

2

One of the prerequisites for the formation of a thunderstorm is -

the presence of moist air through a considerable depth of the atmosphere 

3

A strong pressure gradient is normally associated with -

An area of strong winds

3

Advection fog differs from radiation fog in that -

it can form at any time of day and may persist for long periods

4

Area forecasts for flights below 20 000 ft are available -

on request from Air Services Australia or MET office 

5

The recommended speed for flight in turbulent conditions is -

A speed, which gives a compromise between excessive structural loads and the stall

5

During cruise you suspect that carburettor ice forming and apply full carburettor heat. The engine immediately loses power and begins to run roughly. Your immediate action should be -

Leave carburettor heat full ON

5

a condition which is most likely to produce mountain wave activity -

a stable layer of air near the height of the ridge

6

Select a phenomenon which is most likely to be associated with cirrostratus cloud -

the halo effect

6

The most likely cause of turbulence over land on a hot day is -

  thermal activity

7

The initial effect of accumulating clear ice on an aeroplane in flight will be -

An increase in stalling speed

8

A wind blowing up sloping terrain during the day could be -

anabatic

9

an indication which would be associated with a sudden decrease in headwind component during an approach to land -

A decrease in indicated airspeed and an increase in rate of descent

9

The validity period of a TTF is -

3 hr from the time of the report with which it is associated

9

A TAF is a statement of the conditions expected for a specified period in the air space within -

5 nm of the centre of an aerodrome

10

A hazard that dust storms are most likely to produce is -

  severe visibility restriction over a widespread area to heights above 10000 ft 

11

When air temperature increases with height through a layer of the atmosphere, the probability of vertical motion is -

Low as rising air becomes cooler than its surroundings

11

The flying conditions above a layer of small cumulus clouds are likely to be -

Smooth 

12

A sudden increase in head wind component during an approach to land will, with altitude and power constant, cause the airspeed to -

Increase and then return to normal 

12

The pressure system which gives rise to a subsidence inversion is -

anticyclone 

13

The strength of the pressure gradient force depends most on -

The spacing of the isobars

13

You would expect calm conditions at an aerodrome in the morning to persist for a longer period if -

Skies are overcast with stratus cloud 

13

the cloud type which is most often associated with mountain wave activity -

altocumulus lenticularis [ lenticular] 

14

the latitude at which there would be the greatest difference between the gradient wind and the actual wind at 5000 ft -

5 degrees S

15

In an area of towering cumulus clouds, select a location, relative to the clouds, in which the least amount of turbulence is usually found -

Between the clouds 

15

An aerodrome weather report is designated as SPECI when -

the weather conditions are fluctuating about or are below specified criteria 

16

The type of precipitation from stratus is most likely to be -

Drizzle

17

A thunderstorm can occur well after a cold front has passed because -

  the surface over which the cold air is passing is increasingly warmer than the cold air mass 

19

The layer of the atmosphere in which most convection takes place is -

the troposphere

20

A thunderstorm is active approximately 10 km from an aerodrome. A hazard for which a pilot approaching to land at the aerodrome should be on the alert is -

Severe low-level wind shear
