BetaDraxon VR Training SyllabusRemove Power
Virtual RealityDescription
This lesson trains the correct and safe procedure for disconnecting a Ground Power Unit (GPU) from an aircraft at the end of turnaround operations. Trainees learn to communicate effectively with the cockpit crew, follow the precise power-down sequence, and handle all equipment and safety items in a controlled, methodical manner to maintain apron safety and prevent equipment damage.
Lesson Overview
- 1Request and receive cockpit confirmation to disconnect GPU power
- 2Turn off GPU power output and engine in the correct order
- 3Disconnect and stow the power cable at the GPU
- 4Turn off GPU ignition and complete final equipment shutdown
Skills Acquired
- Perform coordinated GPU power removal and shutdown sequence with cockpit confirmation
- Shut down GPU power systems following correct operational sequence
- Maintain procedural discipline to prevent power surges or tripping hazards
Lesson Procedure
- The exercise begins beside the running GPU, which is supplying power to the aircraft at the end of turnaround.
- The trainee moves to the correct position beneath the cockpit and requests permission to disconnect, receiving visual confirmation from the pilot.
- Returning to the GPU, they switch off the power output first, then shut down the engine in the proper sequence.
- At the aircraft power receptacle, the plug is removed carefully with both hands, and the suspension hook is released.
- The power cable is carried back and secured neatly in the GPU’s cable holder.
- The trainee completes the final shutdown by pressing the ignition button to power off the GPU completely.
- The procedure ends with all cables stowed and the apron ready for pushback operations.
