Question 1045Navigation 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. The dry bulb thermometer reads 54°F and the wet bulb thermometer reads 50°F. How would you encode the air temperature groups in the report?

AI Explanation
The correct answer is B) 10122, 2008/.
The air temperature groups are encoded as follows:
- The dry bulb temperature of 54°F is encoded as 10122 (1st digit = 1 for 10s, 2nd & 3rd digits = 01 for 10, 4th digit = 2 for 2°F).
- The wet bulb temperature of 50°F is encoded as 2008/ (1st digit = 2 for 20s, 2nd & 3rd digits = 00 for 0, 4th digit = 8 for 8°F, 5th digit = / to indicate the wet bulb).
The other options are incorrect because:
- A) and C) do not correctly encode the wet bulb temperature.
- D) encodes the wet bulb temperature as 50°F instead of 2008/.
