19
Q

The term used to describe a sudden change in windspeed and/or direction from the surface to about 2000ft AGL is (low level Windshear/mountain wave turbulence)?

A

Low Level Windshear.

20
Q

True or False. Forecast strong winds gusting to high speeds and/or change in wind direction above a temperature inversion are signs of the likely presence of a strong wind gradient or Windshear?

A

True.

21
Q

Are all thermals visible?

A

No.

22
Q

Do thermals pose a greater problem to Aircrafts during cruise or on approach to land? What hazard do they create?

A
  • Approach to Land.

- Difficult to control flight path.

23
Q

When approaching to land in hot, dry, inland areas, dust devils can suddenly form and spin across the runway in front of the Aircraft. What is the major hazard to Aircrafts in this situation (structural damage/difficulty in control)?

A

Difficulty in Control.

24
Q

For thermals and/or dust devils to form, the atmosphere in the lower levels must be (stable/unstable)?

A

Unstable.

25
Q

Which of the following meteorological phenomenon normally rises to a higher level in the atmosphere (dust devils/thermals)?

A

Thermals.

26
Q

In ATIS broadcasts, wind direction is given in (true/magnetic) whereas in area forecasts (ARFORs) and aerodrome forecasts (TAFs), it is given in (true/magnetic)?

A
  • Magnetic.

- True.

27
Q

In an aerodrome weather report or a TAF, what term is used to indicate the following conditions are visibility of 10km or more, no cloud below 5000ft AGL and no cumulonimbus cloud with no weather phenomenon?

A

CAVOK.

28
Q

Cloud base in an ARFOR is given (AGL/AMSL)?

A

AMSL.

29
Q

Cloud base in a TAF is given (AMSL/AGL)?

A

AGL.

30
Q

In an ARFOR, how is cloud amount of 5 to 7 OKTAs indicated?

A

BKN (Broken).

31
Q

Is the height of both cloud base and cloud tops given in TAFs and ARFOR?

A
  • No (TAF).

- Yes (ARFOR).

32
Q

What is the abbreviation used in forecasts to indicate that changes in prevailing conditions are expected to last for between 30 and 60 minutes?

A

TEMPO.

33
Q

Changing in prevailing conditions which are forecast to last less than 30 minutes are indicated by the abbreviation?

A

INTER.

34
Q

What is indicated by the abbreviation FM in a forecast?

A

A significant change in conditions is expected to be of a more lasting nature than TEMPO and INTER.

35
Q

In a TAF, the wind forecast as 01010G25KT. What does this mean?

A

Wind is coming from 010T at speed of 10kts and Gust of 25kts.

36
Q

In a TAF, what is meant be VRB05KT?

A

Variable Winds of 5kts.

37
Q

The wind in an aerodrome forecast (TAF) or a weather report (METAR) is shown as 00000. What does this mean?

A

Wind is calm.

38
Q

How is the visibility indicated in a TAF if it is above 10km?

A

9999.

39
Q

Forecasts are statements of (actual/expected) conditions and weather reports are statements of (actual/expected) conditions?

A
  • Expected.

- Actual.

40
Q

TAFs are issued for a specified period in the Airspace within a radius of (5NM/10NM) from the centre of the aerodrome for which they are issued?

A

5NM.

41
Q

What type of forecast (as a minimum) would you need for a flight to the training area and back?

A

ANFOR.

42
Q

An aerodrome weather report issued routinely every hour or half hour and which is a statement of actual existing conditions at that time, is known as a (METAR/SPECI)?

A

METAR.

43

01:15 UTC, 13/12/XX
TAF YBHI 130115Z 1302/1314
VRB05KT 9999 RASH SCT040
INTER 1305/1311 3000 TS BKN040CB
RMK
T 32 34 32 25 Q 1019 1017 1017 1018

a) For how long is the forecast valid and between what times?
b) What is the visibility and is it likely to remain the same for the whole period?
c) Between what times is the visibility forecast to deteriorate?
d) For what periods is the visibility likely to deteriorate, and what is the forecast visibility during these periods?
e) During the period of variation from the basic forecast, what amount, type and base of cloud is estimated?

A

a) 12hours (between 0200 and 1400).
b) 10km and visibility will change.
c) 0500 and 1100 on 13th.
d) 30mins or less. 3000 metres.
e) 5-7 OKTAs cumulonimbus base 4000ft AGL.

44
Q

An ARFOR forecast the following cloud:

ISOL EMBD CB 3000/4000
BKN ST 1000/4000 IN RA/TS
OVC NS 2000/28000 LYR

a) Interpret the forecast cloud amount, type, base and top?
b) What cloud type has the greatest coverage and what is its base?
c) With this forecast covering your training area, would VFR flight be possible in the area? Give reasons.

A

a) Isolated embedded cumulonimbus, broken status, and overcast nimbostratus.
b) Overcast nimbostratus with base at 2000ft AMSL.
