See Aerodrome Forecast (TAF and TAF3) in the Bureau of Meteorology Aviation Weather Services Knowledge Centre.

7. When are AIRMETs issued?

Question:

Only when the occurrence, or expected occurrence, of specified enroute weather phenomena are showing an improvement in conditions

To provide information on the location, extent, expected movement or forecast location, and change in intensity of specified phenomenon

When the occurrence, or expected occurrence, of specified enroute weather phenomena are not already included in the graphical area forecast (GAF)

Only to alert pilots to phenomena of a greater degree of severity than that of a SIGMET

Correct.

See AIRMET in the Bureau of Meteorology Aviation Weather Services Knowledge Centre.

Incorrect.

The correct answer is 'when the occurrence, or expected occurrence, of specified enroute weather phenomena are not already included in the graphical area forecast (GAF)'.

8. What is 0900 Australian Eastern Daylight Time (AEDT) on the 3 November converted in Coordinated Universal Time (UTC)?

Question:

032300 UTC

022300 UTC

032200 UTC

022200 UTC

The correct answer is '022200 UTC'.

See paragraph 5 AIP GEN 2.7.

9. Given an elevation of 1,200 ft, a QNH of 1023 hPa, and an air temperature of 30 °C, the density height will be closest to:

Question:

3,600 ft

2,900 ft

3,200 ft

4,300 ft

Correct.

To find pressure height: 1013 – 1023 = -10 x 30 = -300, -300 + 1,200 = 900 ft.

Then to find density height: ISA temp = 15 - (900/1000 x 2) = 13.2, ISA deviation = 30 - 13.2 = 16.8, 16.8 x 120 = 2,016, density height = 2,016 + 900 = 2,916 ft.

Incorrect.

The correct answer is '2,900 ft'.

To find pressure height: 1013 – 1023 = -10 x 30 = -300, -300 + 1,200 = 900 ft.

Then to find density height: ISA temp = 15 - (900/1000 x 2) = 13.2, ISA deviation = 30 - 13.2 = 16.8, 16.8 x 120 = 2,016, density height = 2,016 + 900 = 2,916 ft.

10. What does FM in a TAF mean?

Question:

The weather conditions are expected to reach or pass through specified amendment criteria at a regular or irregular rate

Significant intermittent variations will occur from the prevailing conditions previously given in the TAF

When one set of prevailing weather conditions is expected to rapidly change to a different set of prevailing weather conditions

The following information relates to turbulence (if forecast), temperatures, and QNH

Correct.

See Aerodrome Forecast (TAF and TAF3) in the Bureau of Meteorology Aviation Weather Services Knowledge Centre.

Incorrect.

The correct answer is 'when one set of prevailing weather conditions is expected to rapidly change to a different set of prevailing weather conditions'.

See Aerodrome Forecast (TAF and TAF3) in the Bureau of Meteorology Aviation Weather Services Knowledge Centre.
