An aircraft descends from 9,500 ft to 2,000 ft at a constant rate of descent of 1,500 ft/min. How long will the descent take?
Answer
5 minutes
Explanation
The altitude loss is 7500 ft. At 1200 ft/min, time is $7500/1200=6.25$ minutes, approximately 6 minutes among the choices. **Key takeaway:** Descent time equals altitude loss divided by ROD. **Glossary:** ROD: rate of descent.
