Final answer:
The secondary flight controls on the 737 include flaps, spoilers, slats, elevator trim, and rudder trim.
Step-by-step explanation:
The secondary flight controls on the 737 include:
- Flaps: These are located on the trailing edge of the wings and are used to increase lift during takeoff and landing.
- Spoilers: These are panels that are raised on the wings to disrupt the airflow and reduce lift, assisting with the braking and control of the aircraft.
- Slats: These are located on the leading edge of the wings and are used to increase lift at lower speeds.
- Elevator Trim: This control surface is used to adjust the position of the aircraft's horizontal stabilizer, allowing for fine adjustments in pitch.
- Rudder Trim: This control surface is used to adjust the position of the aircraft's vertical stabilizer, allowing for fine adjustments in yaw.
