Question 13Navigation Problems

The correct answer is B) 279°T. To arrive at this answer, we need to convert the given course of 281°pgc (compass course) to the true course made good. First, we need to apply the variation of 24°W to the compass course, which gives us 281°pgc - 24°W = 257°T. Next, we need to apply the deviation of 4°E, which gives us 257°T + 4°E = 261°T. Finally, we need to apply the gyro error of 2°W, which gives us 261°T - 2°W = 279°T. The other options are incorrect because they do not properly account for the variation, deviation, and gyro error in the correct sequence to arrive at the true course made good.
