What is the takeoff ground roll distance (no obstacle)?

• A. 725 feet
• B. 1,200 feet
• C. 900 feet
• D. 650 feet

Answer: (A)

Takeoff ground roll is the distance the airplane covers on the runway from the moment you start the takeoff roll until the wheels leave the surface. With no obstacle present, you only count that initial rolling distance up to liftoff, not any additional distance needed to climb over an obstacle. In standard conditions for a typical light airplane, that ground roll is about 725 feet. The other numbers would reflect longer distances under different circumstances or different definitions (like distance to clear an obstacle or total takeoff distance), so they don’t apply to the no-obstacle ground-roll scenario. That's why 725 feet is the best match.
