🔍 Key Concepts

• Difference between a gyro compass course (pgc) and a standard magnetic compass course (psc) • How to apply variation and deviation when converting courses and bearings • Remembering the correct order of applying corrections: True–Magnetic–Compass (T–M–C) or Compass–Magnetic–True (C–M–T)

💭 Think About

• Start from the course per gyro compass (pgc) and think about which corrections you need to apply to reach a standard magnetic compass reading. • Consider the sign (E or W) of both gyro error and any magnetic corrections—do they make the compass reading larger or smaller? • Use a systematic method (like the T–M–C table) to keep track of each step and avoid mixing up the direction of corrections.

✅ Before You Answer

• Verify what information you were given earlier in the problem about gyro error, variation, and deviation—you must use those values correctly. • Check that you applied the corrections in the correct sequence and with the correct sign (adding vs. subtracting). • Compare your final compass course with the original gyro course: does the direction and size of the change make sense given the errors involved?
