Answer the following questions
Test Mode
Training Mode
1. At what times are WAFC significant weather charts produced?
At midnight and midday only
At 0000 and 1200Z
At 0000, 0600, 1200, 1800 LMT
At 0000, 0600, 1200, 1800 UTC
2. On WAFC significant weather charts what do the letters CB imply?
Moderate icing and turbulence
Moderate to severe icing and turbulence and hail
Moderate to severe icing and turbulence
Severe icing and turbulence and hail
3. Why are indications about the height of the tropopause not essential for flight documentation in the tropics?
The tropopause is generally well above the flight level actually flown.
The meteorological services are unable to provide such a chart
Tropopause information is of no value
The temperatures of the tropical tropopause are always very cold and therefore not important
4. Which weather chart gives information about icing and the height of the freezing level?
500 hPa chart
700 hPa chart
Surface chart
Low Level Significant weather chart
5. How are well separated CB clouds described on the Significant Weather Chart?
OCNL CB.
ISOL CB.
EMBD CB.
FREQ CB.
6. When are WAFC significant weather charts produced?
Every 12 hours
Every 3 hours
At midnight and midday only

TAF and METAR
8. On WAFC significant weather charts, jet streams are given flight levels. To what does this flight level refer?
The flight level of the mean wind in the jet stream
The flight level of the maximum wind in the jet stream
The average height of the jet stream
The highest flight level where the winds are more than 60 knots
9. What information is given on a Significant Weather Chart?
The significant weather in a period 3 hours before and 3 hours after the time given on the chart
The significant weather forecast for a period 6 hours after the time given on the chart
The significant weather forecast for the time given on the chart
The significant weather that is observed at the time given on the chart
10. What is the validity time for a WAFC significant weather chart?
30 minutes
6 hours
For a fixed single time only
3 hours
11. What does the symbol with an “H 450” inside it indicate on a significant weather chart?
The center of a tropopause “high”, where the tropopause is at FL 450
The lower limit of the tropopause
The center of a high pressure area at 450 hPa
The upper limit of significant weather at FL 450.
