According to the performance specifications, what is the ground roll at take-off?

• A. 700 ft
• B. 725 ft
• C. 750 ft
• D. 800 ft

Answer: (B)

Ground roll is the distance the airplane travels on the runway from brake release until it lifts off. The performance data for the Cessna 152 specify 725 ft as the ground roll under the standard takeoff conditions (typically level, hard-surface runway, no wind, maximum gross weight). This means you should expect about 725 ft of runway to accelerate to liftoff speed under those conditions. Real-world results can vary with weight, density altitude, wind, runway surface, and slope. The other distances in the data correspond to different performance figures (like distance to clear a 50 ft obstacle) or different conditions, not the ground roll.
