Question 911Navigation General70% to pass
Your vessel is participating in the Voluntary Observing Ship Program, you are preparing WS Form B-80 as seen in illustration D041NG below. One-half of the sky is covered with clouds, and the anemometer indicates that the apparent wind is from 340° relative at 14 knots. You are on course 307°T at 12.6 knots. How should you encode group Nddff?
AI Explanation
The correct answer is D) 42205.
To encode the group Nddff, we need to consider the following information:
- One-half of the sky is covered with clouds, which corresponds to cloud cover code N = 4.
- The apparent wind is from 340° relative at 14 knots. Translating this to the ddff format, we get dd = 34 (340°) and ff = 14 (14 knots).
The other options are incorrect because:
A) 43013 does not match the given wind direction and speed.
B) 53414 does not match the given cloud cover.
C) 54013 does not match the given wind direction and speed.
