I have never seen such a device with a magnetic heading references integrated into it. Given that it appears to have flight director and autopilot command bars integrated into it, that kind of an instrument generally goes by the name flight command indicator (FCI), but these devices have all kinds of different names, e.g. artificial horizon, attitude indicator, attitude reference indicator, etc.

Is there a special name for the type of attitude indicator or artificial horizon that is more or less a complete sphere and includes lines to show the aircraft heading? I've seen them in the cockpits of military aircraft from the 1960s.

Now, according to the cockpit layout for the F-4 fighter, the instrument appears to be called an Attitude Direction Indicator (ADI).

Sure thing, partner! In the aviation world, we use a fancy-sounding term called "attitude indicator" to refer to a type of instrument that helps us pilots keep the airplane level and flying straight. Now, there's a special kind of attitude indicator that's shaped like a sphere and also tells us which direction we're heading. We call this little gizmo a "spherical attitude indicator with heading." Pretty nifty, ain't it?
