Question 686Navigation General70% to pass
Your radar has a beam width of 2°. The radar gyro bearing of the right tangent of an island is 316°. The gyro error is 1°E. Which true bearing should be plotted on the chart?
AI Explanation
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.
