Flight Controls and the Three Axes (Interactive 3D)
All controls neutral.
Movement off: surfaces only.
Keyboard: click the model, then ←→ yoke · ↑ push · ↓ pull · Z/X rudder · Space center · R reset view
This is a simplified model for learning: deflections are exaggerated, and “airplane movement” is an illustration, not a flight simulator.
Guided practice
Use the model above. Each step checks off by itself when you do it.
- Turn the yoke right to 50% or more. Watch the right aileron go up and the left go down.
- Pull the yoke back to 50% or more. The elevator's trailing edge rises.
- Press the right rudder pedal to 50% or more. The rudder swings right.
- Turn on “Show airplane movement” and roll into a right bank of 20° or more.
- Roll back to wings level (within 5°) with the yoke.
Done. You've used every primary control. Why does a lowered aileron raise its wing? It increases that wing's camber, and so its lift.
Quick challenge
Four quick tasks using the model.
How the controls work
An airplane rotates around three axes, all passing through its center of gravity. Each primary flight control rotates it around one axis.
| You do | Surface moves | Axis | Airplane |
|---|---|---|---|
| Yoke right | Right aileron up, left down | Longitudinal (nose–tail) | Rolls right |
| Yoke left | Left aileron up, right down | Longitudinal | Rolls left |
| Yoke back | Elevator trailing edge up | Lateral (wingtip–wingtip) | Pitches up |
| Yoke forward | Elevator trailing edge down | Lateral | Pitches down |
| Right pedal | Rudder right | Vertical | Yaws right |
| Left pedal | Rudder left | Vertical | Yaws left |
A control surface changes the camber, and so the lift, of the part it's attached to. A lowered aileron adds lift to its wing; a raised one reduces it. The lowered aileron also creates more drag, which yaws the nose away from the turn (adverse yaw). That's why pilots add rudder in the direction of the turn to keep it coordinated.
What this model leaves out
- Real deflection limits are smaller and come from the aircraft's type data and POH.
- Real airplanes have stability, adverse yaw and airspeed effects. This model just turns input into a steady rotation.
- Your airplane may use a stabilator, Frise or differential ailerons, or other designs.
