Advanced Tuning

The sliders on the Tuning page set how strong each effect is. Advanced Tuning shapes how that strength changes through the flight, such as a lighter stick on approach and a firmer one near Vne, or a stall buffet that starts earlier.

What a response curve is

A response curve plots an effect's strength, going up, against the thing that drives it, going across. Some examples:

Pitch load against indicated airspeed. A low curve at approach speed gives a light stick; a high curve near Vne gives a stiff one.
Stall buffet against the margin to the stall angle. The less margin is left, the stronger the buffet.

The curve sets the shape. The effect's slider on the Tuning page still sets the overall level, so 100% on most curves means the full level of that slider.

To open the page, click Advanced Tuning in the PRO section of the sidebar. It edits the active profile, named at the top left with a Starter or Saved tag. To edit another profile, choose it from the profile menu at the top of the window. Opening the page never arms the stick.

Find an effect

The effect list on the right is grouped, such as Stick feel, Airframe, Engine, Ground, Mechanical and Helicopter. Click a group name to open or close it.
Type in Search effects to find an effect by name.
All lists every effect. Edited lists only the effects with unsaved changes, which also carry an orange dot.

A tag at the top right of the curve shows what the effect is doing now. Point at it to see the reason.

Tag	What it means
active 58%	The effect is running now, at 58%.
off now	The effect can run, but its input gives it nothing to do at the moment.
event	A one-shot effect, such as touchdown, waiting for its next event.
n/a	The simulator does not send the input this effect needs.
rotorcraft	A helicopter effect, and the profile is set up for a fixed-wing aircraft.
No live data	No simulator data is arriving. Connect a simulator and arm to see where the effect is on its curve.

Built-in or Custom

Every effect has a built-in response. Click Custom in the band above the graph to use your own curve instead, or Built-in to go back. Your curve stays in the profile while Built-in is selected.

When you change the shape of a curve, Custom switches on by itself and the page says Custom curve enabled. Undo restores the previous settings.

Pitch load and roll load share this choice and the full-scale airspeed, but keep separate shapes. Center pitch and center roll share the choice too.

Read the graph

Figure 2. The pitch load editor: the curve with Vs0, Vs and Vne marked, the How this curve works guidance and the Curve points table.

The axis across the bottom is the input, with its unit, such as Indicated airspeed (kt). On the stall buffet curve, the stall is at the right edge.
The axis going up is the output in percent. The label above the graph says what 100% means for this effect, such as Spring stiffness (%) or Strength (% of the slider level).
On airspeed curves, dashed lines mark the aircraft's speeds, such as Vs0, Vs and Vne. They come from the Aircraft Library and the simulator.
The green dot and dotted line show where the flight is now. The line under the readout box gives it in numbers, such as now 95 kt curve 58%. It says law in place of curve while the built-in response is in use.
A grey dashed line shows the saved curve, or the built-in law when the profile has no saved curve. Clear Saved curve or Built-in law under the graph to hide it.
Point anywhere on the graph and the readout box gives the response at that input.

How this curve works explains what 100% means for this effect and which points to move for the feel you want. Its last line compares the saved and current response at the selected point.

Center pitch has two curves. Click Travel for the centering force against stick travel, or Trim for the pitch spring stiffness against the trim position.

Edit a curve

To do this	Do this
Move a point	Drag it on the graph, or type new values in its row of the Curve points table. Click a point or its number to select it.
Add a point	Click Add point to add one halfway between the selected point and the next. You can also click an empty spot on the graph and choose Add point here.
Remove a point	Click × in its row, or click the point on the graph and choose Delete point.
Undo a change	Undo and Redo step through the changes to the selected curve, up to 50 steps.
Start from a standard shape	Click Presets… and choose Linear, Progressive or, for most effects, Built-in law.
Use the same shape on both axes	On a pitch curve, click Copy to roll. On a roll curve, the button reads Copy to pitch.
Change the airspeed range	Type a new value in Full-scale airspeed (kt). This sets the right end of the pitch and roll load curves. Both curves stretch or shrink, and each point keeps its percentage.

Inputs must increase from one point to the next, and outputs stay between 0 and 100%. On the airspeed curves and some others, the first and last inputs stay fixed. The note under the table tells you which rule applies.

Save or discard your changes

Changes apply to the active profile as soon as you make them, so you feel them on the stick straight away if it is armed. Save to keep them.

Figure 3. Three curves changed on the C172 starter: the stall buffet curve is being edited, and orange dots mark the edited effects in the list.

The button at the top shows how many curves you have changed, such as 3 curves changed. Click it to list only the edited effects.
Save changes writes the curves into the active profile, together with any other unsaved changes from the Tuning page.
On a built-in starter the button reads Save as new profile. Type a Profile name and click Save profile. Pro creates a new profile and never overwrites the starter.
Click the arrow beside an edited effect in the list to return that curve to the saved profile. Reverting pitch load or roll load also restores the settings they share.

The ••• button holds three more actions:

Save as… saves the active settings as a new profile under a name you choose.
Discard all… returns every unsaved change, on Tuning and on Advanced Tuning, to the saved profile. Pro asks you to confirm first.
Open Tuning opens the Tuning page.

To go back to an earlier saved version of a profile, see Profile History.

Example: a C172 that is lighter on approach and firmer near Vne

Load a Cessna 172 in the simulator and pick its profile, such as the Cessna 172 Skyhawk (G1000) starter.
Open Advanced Tuning and click Pitch load under Stick feel.
Click Custom if it is not already selected.
Find the point nearest your approach speed, about 65 kt in a C172. Lower its value in the Stiffness (%) column, or drag the point down.
Find the Vne 163 line. Select the last point before it and click Add point. The new point lands halfway to the next one.
Drag the new point up, so the stiffness climbs earlier on the way to Vne.
For the same shape in roll, click Copy to roll.
Arm the stick and fly a circuit. Watch the green dot move along the curve as your speed changes.
Click Save as new profile, type a name and click Save profile.

This curve tops out at 100% of the aircraft's reference stiffness. To make the whole pitch axis heavier, raise Elevator load on the Tuning page or in the Live Dashboard.

When something looks wrong

Problem	What to do
The aircraft's speeds are not marked.	The marks appear only on airspeed curves, and only once the aircraft is loaded in the simulator. An aircraft without an Aircraft Library entry may have none.
There is no green dot.	No live data is arriving. Connect a simulator and arm. A missing dot does not mean the effect is at zero.
A changed curve feels no different.	Check that Custom is selected and the tag says active. A curve shapes an effect but cannot switch it on, and it has nothing to shape while the effect's slider is at zero.
The roll curve changed when you edited pitch.	Pitch load and roll load share Built-in, Custom and the full-scale airspeed. Their point shapes stay separate.
A point will not move or cannot be added.	Read the message under the graph. Points must stay in order and the end points of some curves are fixed. Airspeed curves hold 4 to 10 points; other curves hold up to 32.
