Which performance parameter is described as poor due to overweight?

• A. Angle of climb
• B. Takeoff speed
• C. Rate of climb
• D. Stall speed

Answer: (B)

When the aircraft is heavier, it must generate more lift to become airborne. That means the minimum airspeed needed for takeoff increases with weight. So, overweight pushes the required takeoff speed higher, making takeoff performance poorer because you have to accelerate to a faster speed before you can lift off. This also tends to lengthen the takeoff roll and reduce safety margins. (Other weight-related effects—like higher stall speed and lower rate of climb—also worsen with weight, but the direct takeaway here is that takeoff speed rises with overweight.)
