30. Given TC 183°, WCA +11°, MH 198°, CH 200°, find TH and deviation.
Answer
TH 194°, DEV −2°
Explanation
The true heading is $183°+11°=194°$. The compass heading is 2° greater than magnetic heading; with the question bank's sign convention this is DEV −2°. **Key takeaway:** Deviation is the compass-to-magnetic correction. **Glossary:** CH: compass heading; DEV: deviation.
