How are flight control surfaces positioned during flight?

The positioning of flight control surfaces during flight is predominantly achieved through dedicated electric servos. These electric servos provide precise control and rapid response times, making them ideal for managing the dynamic demands of aircraft flight. They convert electrical signals from the flight control systems into mechanical movement, which positions the control surfaces such as ailerons, elevators, and rudders.

Using electric servos allows for a more compact and efficient design compared to traditional systems. They also support advanced features such as automated flight controls and enhanced stability, which are critical for modern unmanned aerial vehicles like the MQ-9. The reliance on electric servos in this context underscores the movement towards more electronic and automated systems in aviation, providing improved accuracy and reliability in flight control.
