Question 1

(Refer to METAR: KXYZ 121853Z 18015G25KT 1/2SM +TSRA BKN008 OVC015 13/12 A2992) What are the current wind conditions?

Accepted Answer

Wind from 180 degrees at 15 knots, gusts to 25 knots.

Answer

The wind group `18015G25KT` is decoded as wind from 180 degrees true at a sustained speed of 15 knots. The 'G25' portion indicates that wind is gusting up to 25 knots.

Question 2

(Refer to TAF: KABC 121730Z 1218/1318 15012KT P6SM BKN030 FM130200 18010KT P6SM SCT040) What weather is forecast for 0300Z on the 13th?

Accepted Answer

Wind from 180 degrees at 10 knots, scattered clouds at 4,000 feet.

Answer

The `FM130200` group indicates a rapid change (FROM) occurring at 0200 Zulu on the 13th. The forecast weather after this time is wind from 180 degrees at 10 knots, visibility greater than 6 statute miles, and scattered clouds at 4,000 feet AGL.

Question 3

(Refer to METAR: KXYZ 121853Z AUTO 18015G25KT 3SM -RA BKN008 OVC012 13/12 A2992) What is the reported ceiling?

Accepted Answer

800 feet AGL.

Answer

A ceiling is defined as the height of the lowest layer of clouds reported as broken (BKN) or overcast (OVC). In this METAR, the lowest such layer is `BKN008`, which corresponds to a ceiling at 800 feet AGL.

Question 4

The valid period of a routine Terminal Aerodrome Forecast (TAF) is typically:

Accepted Answer

24 hours.

Answer

Standard TAFs are issued four times a day at 0000Z, 0600Z, 1200Z, and 1800Z. They are typically valid for a 24-hour period, though some international locations may have 30-hour TAFs.

Question 5

In a METAR, what does the code `VC` indicate?

Accepted Answer

In the Vicinity.

Answer

The code `VC` stands for 'Vicinity,' which means the specified weather phenomenon is not at the airport station itself, but is within 5 to 10 statute miles of the station. For example, `VCSH` means showers in the vicinity.
