Question 1 of 2066636ee928f7522a1c51957d

You desire to make good a true course of 203°. The variation is 19°E, magnetic compass deviation is 2°W, and gyrocompass error is 1°E. A westerly wind produces a 3° leeway. What is the course to steer per standard magnetic compass to make the true course good?

🔍 Key Concepts

• Apply leeway first to find the true course to steer (into the wind), then convert between True–Magnetic–Compass using the correct sign conventions. • Remember the rule for variation and deviation: "East is least (subtract), West is best (add)" when going from True to Magnetic to Compass. • Identify that a standard magnetic compass uses variation and deviation, while gyro error applies only if you’re steering by the gyrocompass.

💭 Think About

• From a westerly wind causing 3° leeway, should your heading (course steered) be more westerly or more easterly than the desired true course? How does that change the true course to steer? • Starting from the adjusted true course, carefully step through: True → Magnetic (using variation) → Compass (using deviation). At each step, are you adding or subtracting based on East/West? • Ask yourself: if you are steering by the standard magnetic compass, do you actually need to apply the gyrocompass error in this problem, or is it a distractor? Why?

✅ Before You Answer

• Be sure you have first corrected for leeway to get the true course to steer before applying variation and deviation. • When converting: T ± Var = M, then M ± Dev = C, double‑check you used subtract for East, add for West when going from True to Magnetic and Magnetic to Compass. • Confirm your final answer is labeled as per standard compass (psc) and compare it to the choices only after all corrections are applied in the proper order.
