Question 1874Navigation General70% to pass
You are on course 146°T. To check the speed of your vessel you should observe a celestial body on which bearing?
AI Explanation
The correct answer is D) 146°.
To check the speed of a vessel, you should observe a celestial body on the same bearing as your course. This allows you to accurately measure the change in altitude of the celestial body over a known period of time, which can then be used to calculate the vessel's speed.
The other options are incorrect because observing a celestial body on a bearing of 000°, 056°, or 090° would not be on the same bearing as the vessel's course of 146°T, and would therefore not provide an accurate speed measurement.
