Question 1 of 2066636ee928f7522a1c51a60a

Your vessel is participating in the Voluntary Observing Ship Program, at 1200 ZT on 31 August, your position is LAT 43°14'S, LONG 175°44'E. You are preparing WS Form B-80 as seen in illustration D041NG below. How should you encode the first three groups after the call sign if you estimate the wind?

🔍 Key Concepts

• YYGGiw group on WS Form B‑80: how day (YY), hour (GG in UTC), and wind indicator (iw) are encoded, especially when wind is estimated. • 99Lala group (latitude): how to code South latitude 43°14' in whole degrees and tenths, and how South vs North is distinguished in the digits. • QcLoLoLoLo group (longitude): how to determine the correct quadrant code Qc for 175°44'E and how to convert minutes to tenths of a degree for the last digit.

💭 Think About

• Which option’s first 5‑digit group matches 31 August at 1200 UTC and uses the correct iw digit for estimated wind, according to the code table? • When you convert 43°14'S to degrees and tenths, what value do you get, and which middle answer choice encodes that correctly for a southern latitude? • Into which quadrant (as defined in the ship synoptic code) does longitude 175°44'E fall, and how should that be reflected in the first digit of the longitude group?:

✅ Before You Answer

• Confirm from the code table which iw digit is used when the wind is estimated rather than measured by anemometer. • Double‑check the conversion of minutes to tenths of a degree for both latitude and longitude before matching to an answer choice. • Verify that the chosen 99Lala and QcLoLoLoLo groups correctly represent southern latitude and eastern longitude using the official quadrant and hemisphere coding rules.
