Order the steps required to convert a True Course (TC) into a Compass Course (CC).
Answer
Start with True Course (TC), Apply magnetic variation to determine Magnetic Course (MC), Apply compass deviation to determine Compass Course (CC)
Explanation
Variation converts a true reference to a magnetic reference. Deviation converts a magnetic compass-related reference to the aircraft's compass indication. Course and heading should not be interchanged, but the north-reference sequence remains true, magnetic, compass. **Key takeaway:** True → magnetic → compass.\n\n**Glossary:** **Compass course**: course direction expressed relative to compass north.
