An aircraft has TAS 120 kt and a 35 kt tailwind. How long does it need to cover 185 NM?
Answer
1 h 12 min
Explanation
With a tailwind, approximate GS = 120 + 35 = 155 kt. Time = 185/155 ≈ 1.194 hours, about 1 h 12 min. **Key takeaway:** Add tailwind to TAS for the along-track groundspeed in this direct calculation. **Glossary:** Tailwind: wind component blowing in the direction of travel.
