Question 686Navigation General

The correct answer is C) 316°. The radar beam width is 2°, meaning the true bearing of the island's right tangent is within ±1° of the radar gyro bearing of 316°. Since the gyro error is 1°E, the true bearing of the island's right tangent should be plotted as 316° on the chart. The other options are incorrect because: A) 313° is 3° off from the radar gyro bearing, which is outside the 2° beam width. B) 314° is 2° off from the radar gyro bearing, which is still outside the 2° beam width. D) 317° is 1° off from the radar gyro bearing, which is also outside the 2° beam width.
