Ground Power Unit
A Ground Power Unit (GPU) is an essential piece of airport equipment that provides electrical power to aircraft when they are parked at the gate or during maintenance. Think of it like a giant power bank or charger for airplanes. When an aircraft's engines are turned off, it needs external power for everything from lights to air conditioning, and that's what a GPU provides. This equipment can be either mobile (on wheels) or fixed (permanently installed at gates). People who work with GPUs need to know how to operate them safely and efficiently to support aircraft operations.
