A descent rate of 550 ft/min for 4 minutes results in altitude loss of?

• A. 1,900 ft
• B. 2,500 ft
• C. 2,200 ft
• D. 2,100 ft

Answer: (C)

Calculating altitude loss during a constant-rate descent is done by multiplying the descent rate by the time spent descending. At 550 ft per minute for 4 minutes, the loss is 550 × 4 = 2,200 feet. Therefore the altitude drop is 2,200 ft. The other numbers don’t fit because they would require a different time or a different rate.
