Basic Flight Controls – Axis Setup

(Where We Tame the Yoke, Wrangle the Rudder, and Throttle Like a Pro)

Now it’s time to tackle the real beasts of the flight deck—your flight control axes. Because if your yoke is limp, your rudder’s confused, and your throttle’s spiky… you're flying a flying brick with cool lights.

✈️ What Is an Axis?

Think of axes (plural of axis, not something you swing at your PC) as the analog controls—smooth, continuous inputs like:

  • Yoke pitch & roll (your classic “push and pull” and “left and right”)

  • Rudder pedals (tail wagging)

  • Throttle(s) (moar power!)

  • Mixture, Prop pitch, toe brakes, spoilers, flaps, coffee temperature knobs (okay maybe not that last one… yet)

If it moves smoothly and isn’t a button, it’s probably an axis.

0.0 (released) to 1.0 (full brake)

Nosewheel Steering

Nose gear steering

Landing Gear

Gear handle (if used as axis)

sim/flightmodel/controls/gear_handle_down

0 (up) or 1 (down)

🎮 Step 1: Axis Configuration

  • On the left panel, click the device you want to configure (like your yoke, throttle quadrant, pedals).

  • Head to the “Axis” tab.

  • You’ll see a list of all your available axis inputs. If it wiggles, it’ll show up here.

  • move the axis you want to configure (wiggle that stick!).
