Which of the following are primary flight controls of the Falcon 2000LXS?

The primary flight controls of the Falcon 2000LXS are essential components that directly influence the aircraft's movement in flight. The correct answer identifies the elevators, rudder, and ailerons as these primary controls.

Elevators are located on the horizontal stabilizer and control the aircraft's pitch, allowing the pilot to raise or lower the nose of the aircraft. The rudder, situated on the vertical stabilizer, governs the yaw movement, enabling the aircraft to turn left or right by directing airflow at the tail. Ailerons are located on the wings and facilitate roll, which allows the aircraft to bank during turns. Collectively, these three components are crucial for the fundamental control of the aircraft in all three axes of motion.

The other options include controls that serve different functions; for instance, while flaps and slats enhance lift during takeoff and landing, they are secondary controls and do not belong to the primary group. Similarly, spoilers are used for drag and descent control rather than primary flight maneuvers, and a vertical stabilizer is a structural component rather than a direct control surface. Thus, the combination of elevators, rudder, and ailerons provides comprehensive control over the aircraft's flight path.
