    FsSimVarId simvarId,
    FsUnitId unitId,
    FsVarParamArray param,

simvarId	The id of a simvar (found using fsVarsGetAircraftVarId).
unitId	The id of an unit (found using fsVarsGetUnitId).

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
