71. TC 220°, TAS 220 kt, wind 270°/50 kt. What is GS?
Answer
185 kt
Explanation
The wind is mostly a crosswind with a component opposing the southwest-bound track. Resolving wind along the track gives a groundspeed of about **185 kt**. **Key takeaway:** Only the along-track wind component directly adds to or subtracts from GS. **Glossary:** Crosswind: wind component perpendicular to track.
