Question 1

Under which of the following conditions is the most severe CAT likely to be experienced?

Accepted Answer

A curved jet stream near a deep trough

Answer

A straight jet stream near a low pressure area

Answer

A westerly jet stream at low latitudes in the summer

Answer

A jet stream, with great spacing between the isotherms

Question 2

Extensive cloud and precipitation is often associated with a non frontal thermal depression because of:

Accepted Answer

Surface convergence and upper level divergence causing widespread ascent of air in the depression

Answer

Surface divergence and upper level convergence causing widespread ascent of air in the depression

Answer

Surface divergence and upper level convergence causing widespread descent of air in the depression

Answer

Surface convergence and upper level divergence causing widespread descent of air in the depression

Question 3

Which statement is correct regarding the ICAO Standard Atmosphere?

Accepted Answer

At MSL temperature is 15°C and pressure is 1013.25hPa

Answer

At MSL temperature is 10°C and the decrease in temperature with height is 1°C per 100m

Answer

At MSL temperature is 15°C and the decrease in temperature with height is 1°C per 100m

Answer

At MSL pressure is 1013.25 hPa and the decrease of temperature with height is 1°C per 100m

Question 4

In temperate latitudes what weather conditions may be expected over land during the summer in the centre of a stationary high pressure zone?

Accepted Answer

Calm winds, haze

Answer

TS, SH

Answer

CB, TS

Answer

NS

Question 5

The range of wind speed in which radiation fog is most likely to form is:

Accepted Answer

Below 5 kt

Answer

Between 10 and 15 kt

Answer

Above 15 kt

Answer

Between 5 and 10 kt

Question 6

The turbulence which occurs at high flight levels (above FL 250) is mainly of the type Clear Air Turbulence. In what way can moderate to severe Clear Air Turbulence affect an aircraft, the flight and the passengers?

Accepted Answer

The turbulence is a small scale one and can cause damage. The manoeuvring of the aircraft will be made more difficult or even impossible. For the passengers the flight will be unpleasant.

Answer

The turbulence can be resembled with the roughness of a washing-board (small scale) and will not have influence on the aircraft and its solidity, but will make flight a little more difficult. The passengers will seldom notice anything of this turbulence.

Answer

The turbulence is a large scale one (waving) so that the aircraft will be difficult to manoeuvre. The passengers will feel some discomfort.

Answer

The turbulence is wave like which makes the flight unpleasant for the passengers but the manoeuvring will not be affected essentially.

Question 7

At the top of orographic waves, in mountainous regions, the cloud most likely to be encountered is

Accepted Answer

Altocumulus lenticularis.

Answer

Cirrostratus.

Answer

Cumulus mediocris.

Answer

Cirrus.

Question 8

A horizontal tailwind gust may cause an aeroplane to:

Accepted Answer

Descend.

Answer

Climb.

Answer

Have no effect on the flight path.

Answer

Climb or descend depending on gust strength.

Question 9

A super-cooled droplet is:

Accepted Answer

A droplet still in liquid state at a temperature below 0°C

Answer

A water droplet that is mainly frozen

Answer

A small particle of water at a temperature below -50°C

Answer

A water droplet that has been frozen during its descent

Question 10

An air mass acquires its basic properties

Accepted Answer

By stagnation of the air for a long period of time over areas having particular characteristics

Answer

By the influence of jet streams

Answer

In the westerlies of the mid-latitudes

Answer

By widespread thunderstorms
