74. TC 270°, TAS 100 kt, wind 090°/25 kt. What is GS?
Answer
125 kt
Explanation
The wind comes from 090°, directly behind an aircraft tracking 270°, so it is a 25 kt tailwind. GS is $100+25=125$ kt. **Key takeaway:** Wind direction is the direction from which wind blows. **Glossary:** Tailwind: wind component assisting forward motion.
