Which performance parameter is described as limited due to overweight?

• A. Maximum altitude
• B. Takeoff speed
• C. Operational range
• D. Angle of climb

Answer: (A)

Weight affects how high an aircraft can climb. As you add weight, the airplane needs more lift and thrust to maintain climb, so the climb rate drops. The maximum altitude, or service ceiling, is defined by the point where the climb rate becomes zero; with extra weight, that ceiling moves lower, meaning overweight directly limits how high you can go. While heavier weight also raises the required takeoff speed, can shorten range, and reduces angle of climb, the question points to the parameter whose limitation by overweight is most directly described, which is the maximum altitude.
