Match each aeronautical Q-code to its corresponding bearing definition: Q-Codes: 1. QDM 2. QDR 3. QTE 4. QUJ Definitions: A. Magnetic bearing from aircraft to station B. Magnetic bearing from station to aircraft C. True bearing from station to aircraft D. True bearing from aircraft to station

The codes distinguish the bearing's north reference and whether it points from the station or toward it. QDR and QTE are station-to-aircraft bearings; QDM and QUJ point from aircraft to station. Reciprocal directions differ by 180°. **Key takeaway:** Check both the reference north and bearing origin. **Glossary:** **Reciprocal**: direction 180° opposite another direction.
