A VDF ground station reports QDR 225°. In which general quadrant is the aircraft relative to the station?
Answer
Southwest
Explanation
A QDR of 225° is a magnetic bearing from the station to the aircraft. Bearings are measured clockwise from north: 180° is south and 270° is west, so 225° lies midway between them, in the southwest quadrant.\n\n**Key takeaway:** QDR locates the aircraft outward from the station.\n\n**Glossary:** **VDF**: VHF direction finding; **QDR**: magnetic station-to-aircraft bearing.
