What are the primary flight controls on a 737?

• A. Elevators and Ailerons
• B. Elevators, Ailerons, and Rudder
• C. Ailerons and Rudder
• D. Rudder only

Answer: (B)

Primary flight controls are the surfaces you use to change the airplane’s orientation in pitch, roll, and yaw. On a 737, these are the elevators on the horizontal stabilizer for pitch, the ailerons on the wings for roll, and the rudder on the vertical stabilizer for yaw. Together, they let the aircraft climb, descend, and turn, while also coordinating the turn with the opposite wing’s roll for smooth, controlled flight. If any one of these is missing, you lose a fundamental axis of control: no elevator means you can’t raise or lower the nose; no ailerons means you can’t roll the wings to start a turn; no rudder means you can’t reliably yaw or coordinate turns, especially in crosswinds. Keep in mind that there are secondary controls like flaps, spoilers, and trim, but they assist or optimize flight rather than provide the basic, primary control over the aircraft’s orientation.
