What is a characteristic of an unmanned aircraft with excess weight during takeoff?

• A. Increased maneuverability
• B. Increased takeoff speed
• C. Decreased fuel consumption
• D. Stable flight

Answer: (B)

When an unmanned aircraft carries excess weight during takeoff, it requires increased takeoff speed to achieve the necessary lift for a successful ascent. This is because the aircraft's heavier weight demands greater aerodynamic forces to counteract gravity and enable lift-off. Consequently, the engines must produce more thrust, which translates into a higher speed needed at the moment of takeoff. In conditions of excess weight, maneuverability can actually decrease rather than increase due to the added mass, which affects the aircraft's handling characteristics. Likewise, fuel consumption typically rises rather than decreases as more power is needed to propel the heavier aircraft, leading to higher fuel usage. Finally, stable flight is not guaranteed with excess weight; in fact, the risk of instability can increase due to the additional stress placed on the aircraft's systems during takeoff, especially if proper operational limits are exceeded.
