🔍 Key Concepts

• Gyro error = True bearing − Gyro bearing (keep track of E/W sign) • Use a range (two lights in line) to know the true bearing of that line from the chart • Difference between per gyro compass (pgc) and true bearing (T)

💭 Think About

• On the chart, find the true bearing of the line formed by Bartlett Reef Light and New London Harbor Light from your position. How do you measure that accurately? • Once you have the true bearing, compare it with the 039° per gyro compass. Which one is larger, and what does that tell you about whether the gyro error is east or west? • Carefully compute the numerical difference between true and gyro bearings. Does that difference more closely match 0°, 2°, or 4° in the answer choices?

✅ Before You Answer

• Verify the true bearing of the range line (Bartlett Reef Light in line with New London Harbor Light) from the chart, in degrees true. • Check that you are using the correct formula: Gyro error = True − Gyro and then convert the sign into E (gyro high) or W (gyro low). • Confirm that you did not accidentally use magnetic or compass bearings; the question is specifically about gyro vs true.
