This lesson introduces the controls and indicators of the Ground Power Unit (GPU). Trainees learn to operate the main physical buttons and the integrated touchscreen display while gaining familiarity with the logic and safety principles of GPU operation during aircraft turnaround.

Display indicators change color to red or grey, and output values reset to zero. This demonstrates how the GPU visually signals a loss of power connection and reinforces awareness of connection status during use.
