How will landing distance be affected by being overweight?

• A. Increased
• B. Decreased
• C. No change
• D. Unknown

Answer: (A)

Weight affects landing distance because heavier airplanes carry more kinetic energy and require a higher approach speed. When the aircraft is heavier, the stall speed rises, so you approach at a higher indicated airspeed to maintain lift. That extra speed means more energy to dissipate once you touch down. Brakes, spoilers, and reverse thrust have a finite ability to decelerate you, so with more energy to remove, you need more runway to come to a stop. While braking forces do increase with weight, they don’t offset the additional energy, so the landing distance grows. Therefore, landing distance increases as weight increases.
