Given QDM 138° and variation 10°E, what is the corresponding QUJ?

QDM is the magnetic bearing from aircraft to station. Convert it to true by adding east variation: $138^\circ+10^\circ=148^\circ$. QUJ is the true bearing from aircraft to station, so the result is 148°, not the reciprocal.\n\n**Key takeaway:** Convert magnetic to true, then preserve the bearing's origin and destination.\n\n**Glossary:** **QDM**: magnetic aircraft-to-station bearing; **QUJ**: true aircraft-to-station bearing.
