🔍 Key Concepts

• Gyro error = True bearing − Gyro bearing (remember East is least, West is best) • Using a chart or exam diagram to find the true bearing of a known transit or range line • Determining whether the gyro is reading high (east) or low (west) compared to true

💭 Think About

• From the chart, what is the true bearing of Trestle "C" when it is exactly in line on the range you are using? • Once you have true and gyro bearings, what is the difference between them, and which side (E or W) should you assign to that difference? • Is the gyro showing a larger or smaller angle than the true bearing? What does that tell you about whether the error is east or west?

✅ Before You Answer

• Be sure you are using the correct true bearing of the range/line of position from the chart (not magnetic or compass) • Apply the formula GE = True − Gyro consistently, keeping track of the sign and then converting that sign into E or W • Double-check whether the numerical difference matches one of the answer choices before deciding on east or west
