Your vessel is participating in the Voluntary Observing Ship Program, at 1200 ZT on 31 July, your position is LAT 24°33'N, LONG 173°05'W. 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?
AI Explanation
The correct answer is D) 01003, 99245, 71731.
1. The first three groups of the weather report should encode the following information:
- Wind direction (degrees)
- Wind speed (knots)
- Barometric pressure (tenths of millibars)
2. Based on the given information, the vessel's position is at latitude 24°33'N and longitude 173°05'W. With an estimated wind, the correct encoding would be:
- Wind direction: 010 degrees
- Wind speed: 99 knots
- Barometric pressure: 1,731 millibars
3. The other options are incorrect because they do not accurately represent the information required for the first three groups of the weather report.
