If an airplane's gross weight is increased, the takeoff speed will

Choices

• remain the same regardless of weight changes.

  Weight directly affects required takeoff speed.

• decrease, requiring a shorter takeoff roll.

  Heavier requires higher takeoff speed, not lower.

• ✓ increase, requiring a longer takeoff roll.correct

  Heavier weight requires a higher angle of attack — and therefore higher airspeed — to produce the lift needed to leave the ground. Higher takeoff speed combined with reduced acceleration (more mass to accelerate) significantly lengthens the takeoff roll.

• increase, but the takeoff roll will remain the same.

  Higher takeoff speed plus more mass to accelerate means a longer roll.
