Match each aeronautical Q-code to its corresponding bearing definition:
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
Answer
1 - A, 2 - B, 3 - C, 4 - D
Explanation
The codes encode both the bearing reference and its direction. QDM and QDR are magnetic; QTE and QUJ are true. QDM and QUJ point from aircraft to station, whereas QDR and QTE point from station to aircraft. Keeping origin and destination clear prevents reciprocal-bearing errors.\n\n**Key takeaway:** Determine both reference north and bearing direction before using a Q-code.\n\n**Glossary:** **True bearing**: direction referenced to true north; **reciprocal**: direction 180° opposite.
