What is the normal climb speed range in flight?

• A. 70-80 KIAS
• B. 60-70 KIAS
• C. 80-90 KIAS
• D. 90-100 KIAS

Answer: (A)

Climb speed is chosen to give good climb performance while keeping a safe margin from stall and within engine cooling limits. In a Cessna 152, the normal climb is performed near the best-rate-of-climb speed, which is about 74 KIAS under standard conditions with the airplane clean. Because weight, density altitude, and temperature vary in flight, a practical normal-climb speed range is about 70 to 80 KIAS. This range provides a solid rate of climb without excessive drag. Going slower than this can bring you too close to stall and reduce cooling and maneuvering margin; going faster than this wastes power and reduces the rate of climb due to increased drag. So, the normal climb speed range best fits safe, efficient climbing in typical climbing conditions.
