Question 1

You cross a jet stream in horizontal flight at approximately right angles. While crossing, in spite of a strong wind of 120 kt, you notice the temperature barely changes. Which of the following statements is correct ?

Accepted Answer

This phenomenon is absolutely normal as you are crossing the jet core.

Answer

This phenomenon does not surprise you at all, since normally no large temperature differences are possible at these heights.

Answer

Since the result of such readings seems impossible, you will have the instruments tested after landing.

Answer

You assume the front associated with the jet stream to be very weak with practically no temperature difference between the two air masses.

Question 2

The QNH of an airport at sea level is 983 hPa and the temperature deviation from ISA is-15°C below FL 100.What is the true altitude of FL 100?

Accepted Answer

8590'

Answer

9790'

Answer

10210'

Answer

11410'

Question 3

Frontal fog is most likely to occur

Accepted Answer

In advance of a warm front

Answer

In rear of a warm front

Answer

In winter in the early morning

Answer

In summer in the early morning

Question 4

Which statement concerning the tropopause is correct?

Accepted Answer

The layer just above the tropopause is absolutely stable

Answer

Above the tropopause no clear air turbulence occurs

Answer

In the ICAO standard atmosphere the tropopause lies lower over the Poles than over the equator

Answer

The temperature at the tropopause is approximately -80°C over the Poles and approximately -40°C over the equator

Question 5

You intend to overfly a mountain range. The recommended minimum flight altitude is, according to the aviation chart, 15000' AMSL. The air mass that you will fly through is on average 15°C warmer than the standard atmosphere. The altimeter is set to QNH (1023 hPa). At what altimeter reading will you effectively be at the recommended minimum flight altitude?

Accepted Answer

14100'

Answer

13830'

Answer

15900'

Answer

14370'

Question 6

During the climb after take-off, the altimeter setting is adjusted at the transition altitude. If the local QNH is 1023 hPa, what will happen to the altimeter reading during the resetting procedure ?

Accepted Answer

It will decrease

Answer

It will increase

Answer

It will remain the same

Answer

It is not possible to give a definitive answer

Question 7

The QNH at an airfield in California located 69 metres below sea level is 1018 hPa. The air temperature is 10°C higher than a standard atmosphere. What is the QFF?

Accepted Answer

More than 1018 hPa

Answer

Less than 1018 hPa

Answer

1018 hPa

Answer

It is not possible to give a definitive answer

Question 8

Precipitation in the form of showers occurs from

Accepted Answer

Convective clouds

Answer

Stratified clouds

Answer

Clouds containing only ice crystals

Answer

Cirro-type clouds

Question 9

The isobars drawn on a surface weather chart represent lines of equal pressure

Accepted Answer

Reduced to sea level

Answer

At a determined density altitude

Answer

At height of observatory

Answer

At flight level

Question 10

In central Europe when is the greatest likelihood for thunderstorms due to warm updrafts?

Accepted Answer

Mid - afternoon.

Answer

Around midnight.

Answer

Early morning.

Answer

Late morning.
