The **fsVarsAircraftVarGet** function can be used to get the value of a specific SimVar.

 

##### Syntax

    FsSimVarId simvarId,
    FsUnitId unitId,
    FsVarParamArray param,
    double* result
);
```

 

##### Parameters

| Parameters | Description                                                                                                                                               |
|------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------|
| `simvarId` | The ID of a simvar (found using `fsVarsGetAircraftVarId`).                                                                                                |
| `unitId`   | The ID of an unit (found using [fsVarsGetUnitId](fsvarsgetunitid/)).                                                                                   |
| `param`    | The parameter which might be mandatory to access the simvar (in case of an indexed simvar for instance). Elements in param can be FsCrc, String or index. |
| `result`   | The value that will receive the value of the simvar if others parameters are right.                                                                       |

{{< /table-wrapper >}}


 

##### Return Values

The function returns a `FsVarError`, 0 means there is no error. In that case, the value of the simvar has been set in `result`.

 

##### Example

``` wasm
FsUnitId unitId = fsVarsGetUnitId("DEGREES");
FsSimVarId simvarId = fsVarsGetAircraftVarId("ATTITUDE INDICATOR PITCH DEGREES");
FsVarParamArray param = FsCreateParamArray("i", 0);
double result = 0;
if (fsVarsAircraftVarGet(simvarId, unitId, param, &result) == FS_VAR_ERROR_NONE)
{
    // valid
}
else
{
    // error
}
```
