Ground Power Unit

A Ground Power Unit (GPU) is a device used to supply electrical power to an aircraft while it is on the ground and not operating its engines. It provides the necessary electricity to run systems like lighting, air conditioning, and avionics without using the aircraft’s own engines or batteries, which helps conserve fuel and reduce wear. GPUs are essential for pre-flight checks, maintenance, and during short stopovers, ensuring the aircraft is fully powered and ready for flight without consuming its internal resources.
