Which statement correctly maps the three primary axes to their controlling flight surfaces on a conventional airplane?

• A. Longitudinal axis runs nose to tail; yaw is controlled by rudder; Lateral axis runs wingtip to wingtip; pitch is controlled by elevators; Vertical axis runs top to bottom; roll is controlled by ailerons.
• B. Longitudinal axis runs nose to tail; pitch is controlled by ailerons; Lateral axis runs wingtip to wingtip; yaw is controlled by elevators; Vertical axis runs top to bottom; roll is controlled by rudder.
• C. Longitudinal axis runs nose to tail; roll is controlled by ailerons; Lateral axis runs wingtip to wingtip; pitch is controlled by elevators; Vertical axis runs top to bottom; yaw is controlled by rudder.
• D. Longitudinal axis runs top to bottom; yaw is controlled by ailerons; Lateral axis runs nose to tail; roll is controlled by elevator; Vertical axis runs wing to wing; pitch controlled by rudder.

Answer: (C)

Understanding the three axes and their controlling surfaces is essential for predicting how a conventional airplane responds to inputs. The longitudinal axis runs nose to tail; rotation about it is roll, controlled by the ailerons. The lateral axis runs wingtip to wingtip; rotation about it is pitch, controlled by the elevators. The vertical axis runs top to bottom; rotation about it is yaw, controlled by the rudder. The correct statement matches exactly this mapping, naming each axis direction and its corresponding control surface. Other options mix up which surface controls which axis or misstate the axis directions, so they don’t reflect the true relationships.
