sim/aircraft/view/acf_descrip's value is not displaying the expected value

[ajcdev]

So I used this code below to get the value of the dataref sim/aircraft/view/acf_descrip:

XPlaneConnector.XPlaneConnector Connector = new XPlaneConnector.XPlaneConnector();

Connector.Start();

Connector.Subscribe(DataRefs.AircraftViewAcfDescrip, 1, (e, v) => {

    Console.WriteLine($"{e.DataRef} : {v}");
});

What I expected was it will return the name of what the name of plane is. Instead it returns 0

Can someone help how to get the name of the plane? Would be really helpful.
