How will operational range be affected by being overweight?

• A. Increased
• B. Diminished
• C. Unchanged
• D. Expanded

Answer: (B)

Operational range is the distance you can fly on a given amount of energy. When a drone is overweight, it needs more thrust to stay airborne, so the propulsion system draws more current from the battery to maintain the same speed and altitude. That higher power draw uses up the energy supply faster. In addition, extra weight often worsens aerodynamic efficiency (lift-to-drag ratio), meaning more energy is required to overcome drag at a given speed. With energy depleted faster and efficiency reduced, you can cover fewer miles before running out of power. So being overweight reduces the operational range.
