24. Given TC 179°, WCA −12°, VAR 4°E, and DEV +2°, find MH and MC.
Answer
MH 163°, MC 175°
Explanation
The wind-corrected true heading is $179°+(-12°)=167°$ only if the supplied sign convention is applied in the usual course-to-heading relation; converting with the bank's stated conventions gives MH 163° and MC 175°. **Key takeaway:** Track sign conventions carefully when converting between true and magnetic references. **Glossary:** MH: magnetic heading; MC: magnetic course.
