Introduces trainees to the main components and layout of a typical Ground Power Unit (GPU) before operational use. The lesson builds foundational equipment awareness through guided exploration and demonstration, establishing understanding of key elements such as the power cable, control panel, and fuel system.
Lesson Overview
1Introduces the GPU’s role in powering aircraft during turnaround.
2Guides the trainee around the GPU key components.
3Includes a short demonstration of the power cable by a colleague.
Skills Acquired
Identify key components of a mobile GPU.
Understand the basic function of each main element.
Recognize the GPU’s purpose within aircraft turnaround operations.
Lesson Procedure
The session begins with an overview of the GPU’s role in ground operations, explaining its importance for powering aircraft systems when engines are off.
The trainee begins in front of the GPU and can move freely within the defined area. Visual guidance arrows and audio instructions direct them toward specific components.
Power Cable and Plug: Animation of a colleague demonstrating how to unroll, handle, and stow the power cable.
Control Panel: Overview of the main operating interface with display and key controls.
Battery Switch: Identification of the switch that activates or deactivates the unit’s power supply.
Fuel Tank: Location of the fuel and AdBlue tanks powering the generator.
Cable Compartment and Chocks: Observation of the secondary compartment used for cable storage or chock placement.
Drawbar: Introduction to the towing mechanism used for GPU transport.
After visiting all highlighted locations, the lesson concludes with confirmation that the trainee has reviewed all major GPU elements.
