Which performance parameter is described as diminished due to overweight?

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

Answer: (A)

When a drone is heavier, it needs more power to maintain flight and to overcome the extra drag from the increased weight. That means it uses energy faster. Range is the maximum distance you can fly on a given amount of energy (fuel or battery). Because overweight drives up energy burn for every mile traveled, the drone can cover less distance before it runs out of energy. So overweight directly reduces operational range. The other aspects, like how steep a climb or how fast you take off, can also be affected by extra weight, but the most noticeable impact on how far you can travel on a single charge is the decrease in range.
