🔍 Key Concepts

• Converting bearings from per gyro compass (pgc) to true bearings using the known gyro error • Plotting lines of position (LOPs) from two simultaneous bearings to fixed charted objects • Reading the resulting fix position from the chart, then extracting the longitude

💭 Think About

• How do you correct a per gyro compass (pgc) bearing to get a true bearing if you know the gyro error and its sign? • Once you have two true bearings to charted objects, how do you plot them on the chart to find the intersection (fix)? • After plotting the fix, where do you read the longitude value, and how precisely must you interpolate between meridians to distinguish between the answer choices?

✅ Before You Answer

• Be sure you are using the correct gyro error and sign convention when converting pgc to true • Confirm you are plotting from the charted positions of Cape Charles Light and Cape Charles Lighted Bell Buoy "14" • Carefully interpolate longitude between meridians to the nearest tenth of a minute so you can distinguish between the four close options
