Which of the following would NOT be a factor in determining the drone's operational range?

The operational range of a drone is primarily influenced by factors such as its weight, battery capacity, and operating altitude. The weight carried affects how much power is needed for flight; a heavier drone requires more energy to maintain flight, which can reduce range. Battery capacity is critical since it determines how long the drone can stay airborne before needing to recharge. Altitude can also play a role, as drones may require more power to operate at higher altitudes due to thinner air reducing lift efficiency.

Spoiler placement, however, relates more to aerodynamics and control during flight rather than directly impacting the operational range. While spoilers can affect lift and drag, their placement does not inherently change the drone’s ability to travel a particular distance. Therefore, it is not a relevant factor in determining operational range in the same direct way as the other options.
