Study Notes
Airplane Control Surfaces
- Airplanes utilize three primary control surfaces: ailerons for roll, stabilator for pitch, and rudder for yaw.
- Control inputs are made using control wheels, control column-tee bar assembly, and rudder pedals.
Aileron Control System
- Each control wheel features a sprocket assembly at the front end of its tube.
- A chain connects the left and right control wheels to idler sprockets on the tee bar.
- Aileron movement is facilitated through primary control cables that engage with the ailerons via a bellcrank and push-pull rods.
Stabilator Control System
- Control of the stabilator is achieved through a cable linked to the bottom of the tee bar assembly.
- This cable interacts with an aft fuselage bellcrank, which in turn operates a pushrod attached to the stabilator’s balance arm.
Rudder Control System
- Rudder pedals are connected to the rudder horn through a cable system, allowing for yaw adjustments during flight.

Description
This quiz covers the fundamental concepts of airplane control, focusing on the three-axis control surfaces: ailerons, stabilator, and rudder. It also explores how these controls are managed through various components such as the control wheel and rudder pedals. Test your understanding of how these mechanisms work together to maneuver an aircraft in flight.
