Question 1 of 2066636ee928f7522a1c51a3b0

The true course between two points is 078°. Your gyrocompass has an error of 2°E. You make an allowance of 3° leeway for a north wind. What gyro course should be steered to make the true course good?

🔍 Key Concepts

• Difference between true course (TC) and gyro course (GC/pgc) • How gyro error East or West changes the relationship between true and gyro headings • How leeway from a north wind affects the course you must steer to make good the desired track

💭 Think About

• Start from the required true course between the points, then adjust that course for the stated leeway. Ask yourself: does a north wind push your track to the north or to the south? So should you steer more northerly or more southerly to compensate? • Once you have the true heading to steer (after leeway), convert it to a gyro course using the sign convention: with an East gyro error, is the gyro reading larger or smaller than the true heading? Adjust in the correct direction. • Compare your final calculated gyro course with the answer choices and consider which one matches the rounded result in whole degrees.

✅ Before You Answer

• Be clear whether leeway is added or subtracted from the desired true course for a north wind. • Confirm the convention for gyro error: GE (E or W) = G - T and decide how an East error affects the gyro reading. • Only after getting the true heading to steer (after leeway) should you convert to pgc (per gyrocompass) and match it to the options.
