What do "primary flight controls" include in the ERJ?

Primary flight controls in the ERJ include the ailerons, elevators, and rudder. These controls are essential for maneuvering the aircraft during flight. Ailerons control the roll of the aircraft, allowing it to tilt and turn sideways, which is crucial for lateral control. Elevators manage pitch, enabling the aircraft to ascend or descend, while the rudder is responsible for controlling yaw, helping the aircraft turn left or right around its vertical axis.

The other options consist of various aircraft systems and controls, but they do not fall under the primary flight controls category. Flaps, air brakes, and spoilers are secondary devices that enhance performance but do not provide the basic directional control during flight. The throttle, yaw damper, and autopilot are systems that aid in engine power management and overall stability but are not categorized as primary flight controls. Lastly, speed brake, elevator trim, and rudder trim are used for adjusting specific flight behavior and aiding pilot workload, but they are not primary controls in maintaining the fundamental aerodynamics of the aircraft.
