Given TC 270°, TAS 100 kt, wind 090°/25 kt, and distance 100 NM, what GS is indicated?
Answer
125 kt
Explanation
The aircraft is travelling west while the wind is from the east, so the wind blows westward and acts as a 25 kt tailwind. GS is 100 + 25 = **125 kt**. **Key takeaway:** Interpret wind direction as the direction from which wind blows. **Glossary:** Wind direction: conventionally the direction from which the wind originates.
