Aviation Standard Test Battery-E (ASTB E) Practice Test

Which components are considered primary flight controls?

1. Ailerons, rudder, and elevators

2. Flaps, slats, and stabilizers

3. Main rotor and tail rotor

4. Throttle and mixture controls

The correct answer is: Ailerons, rudder, and elevators

The primary flight controls consist of ailerons, rudder, and elevators, which are essential for maneuvering an aircraft in three-dimensional space. Each component has a specific function that contributes to the aircraft's control during flight. Ailerons are located on the wings and are responsible for controlling roll. By altering the airflow over each wing, ailerons help the aircraft rotate along its longitudinal axis, allowing it to bank left or right. The rudder is positioned on the vertical stabilizer (tail) of the aircraft and controls yaw, which is the rotation of the aircraft around its vertical axis. Moving the rudder left or right adjusts the direction the nose of the aircraft points, enabling coordinated turns and counteracting adverse yaw that can occur during banking maneuvers. Elevators, found on the horizontal stabilizer, control pitch. By moving the elevators up or down, the pilot alters the aircraft's angle of attack, thus influencing its climb or descent. This control is critical for maintaining a stable flight path and executing takeoffs and landings. Other choices reference components that play different roles. Flaps and slats enhance lift during takeoff and landing rather than acting as primary directional controls. The main rotor and tail rotor are specific to helicopters for
