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?

Correct Answer: Option C — 316°

When measuring the right tangent of an island on radar, beam width distortion causes the echo to appear earlier. The correct tangent is obtained by subtracting half the beam width (1°) from the observed gyro bearing (316°), resulting in 315° gyro, converted to 316° true using 1°E error.
