EASA NAV(A)intermediate
TAS is 180 kt, headwind component is 25 kt, and flight time is 2 hours 25 minutes. What distance is flown?
Answer
375 NM
Explanation
GS = 180 − 25 = 155 kt. The elapsed time is 2 + 25/60 = 2.417 hours. Distance = 155 × 2.417 ≈ 375 NM. **Key takeaway:** Distance equals groundspeed multiplied by time. **Glossary:** **TAS**: Speed through the air; **headwind**: Wind opposing forward travel.
