Question 1

A wind in a terminal area forecast expressed as VRB30G45 would:

Be improbable, since variable wind directions are only associated with light winds and high pressure systems


Question 2

The validity of a METAR is:

A METAR is a report, not a forecast.

Question 3

The wind direction is given in degrees:

Refer to AIP GEN 3.5

Question 4

In a METAR for YAAA, the figures quoted immediately before the QNH read 9/8, and at YBBB they read 10/8. This means that, at place YAAA, the dry bulb is 9C and the:

The closer the dry bulb to the dew point (the spread), the more likely fog is to form.

Question 5

A TAF includes the following:

Refer to AIP GEN 3.5

Question 7

In a TAF, the term FU VV030 means:

Refer to AIP GEN 3.5

Question 8

Refer to AIP ENR 1.7

Question 10

A TAF commences and finishes as follows:

TAF YCOM 070635Z 0708/0720 ... Q 1020 1021 1019 1018
