RE: [SI-LIST] : GND plane heat dissipation

Is this high a temperature consistent with how much power you expected
the pass transistor to dissipate? Is it functioning correctly?

If you were to isolate the ground plane, the area around the transistor
would get even hotter. Should it be heat-sinked? How is the airflow?
