What is typically included in the movable components of the tail assembly?

In the context of aircraft design, the tail assembly typically includes movable components that are essential for controlling the aircraft's pitch and yaw. The correct choice, which includes the rudder and elevators, serves specific functions that are critical to the stability and maneuverability of the aircraft.

The rudder is situated on the vertical stabilizer and is responsible for controlling yaw, which is the left or right movement of the aircraft's nose. By deflecting the rudder to one side, the pilot can effectively steer the aircraft left or right. The elevators, located on the horizontal stabilizer, control pitch, which is the up and down movement of the aircraft's nose. By moving the elevators up or down, the pilot can raise or lower the nose, impacting the climb or descent of the aircraft.

These components are distinct from other parts of the tail assembly that do not have movable functions, such as fixed stabilizers. Fixed stabilizers provide stability but do not contribute to the aircraft's directional control. The engines and propellers, while crucial to flight, are not part of the tail assembly. Similarly, the landing gear is a separate system used for takeoff, landing, and ground operations, not for control during flight. Thus, the rudder and elevators
