Question 2

Fair weather cumulus often is an indication of:

Accepted Answer

Turbulence at and below the cloud level

Answer

Poor visibility at surface

Answer

Smooth flying conditions below the cloud level

Answer

A high risk of thunderstorms

Question 3

The approximate inclined plane of a warm front is:

Accepted Answer

1/150

Answer

1/500

Answer

1/300

Answer

1/50

Question 4

What type of cloud is being described? A generally grey cloud layer with fairly uniform base and uniform appearance, which may give drizzle or snow grains. When the sun is visible through the cloud, the outline is clearly discernible. Sometimes it appears in the form of ragged patches.

Accepted Answer

Stratus

Answer

Altostratus

Answer

Cirrostratus

Answer

Nimbostratus

Question 5

The main factor which contributes to the formation of very low clouds ahead of a warm front is the:

Accepted Answer

Saturation of the cold air by rain falling into it and evaporating

Answer

Warm air moving over a cold surface

Answer

Reduction of outgoing radiation due to clouds

Answer

Saturation of the warm air by rain falling into it and evaporating

Question 6

Wind is caused by

Accepted Answer

Horizontal pressure differences

Answer

The rotation of the earth

Answer

Friction between the air and the ground

Answer

The movements of fronts

Question 7

In case of fronts, what cloud formation is most likely to occur at low levels when a warm air mass overrides a cold air mass?

Accepted Answer

Nimbostratus.

Answer

Altostratus.

Answer

Cumulus.

Answer

Cumulonimbus.

Question 8

What is the approximate maximum diameter of the area affected by damaging winds at the surface caused by a microburst?

Accepted Answer

4 km

Answer

20 km

Answer

400 m

Answer

50 km

Question 9

Mark the correct statement concerning lightning discharge.

Accepted Answer

While flying through air that is electrically charged the aircraft is likely to become a charge carrier itself and can initiate a lightning discharge.

Answer

The probability of a lightning discharge is reciprocally proportional to the strength of the electric field the aircraft intruded.

Answer

The set of possible effects of a lightning discharge does not include welding of aircraft parts such as joints or bearings.

Answer

Because an aircraft acts as a "Faraday's cage", the magnetisation associated with a lightning discharge hardly has an effect on the magnetic compass.

Question 10

The most dangerous icing conditions are encountered in

Accepted Answer

Supercooled precipitation.

Answer

Icy clouds at high levels.

Answer

Unstable clouds at medium levels.

Answer

Zones where the air temperature is below -15°C.
