When working with aircraft on the ground, reliable power is essential. Whether you are starting engines, maintaining avionics, or running systems during servicing, a dependable Ground Power Unit (GPU) keeps operations smooth and safe. At Red Box Aviation, we provide a full range of GPUs and ground support equipment designed for all types of aircraft, from light private planes to commercial fleets.
In this guide, we’ll break down the different types of equipment available, what they’re used for, and why choosing Red Box Aviation makes all the difference.
What is a GPU and Why Do You Need One?
A Ground Power Unit (GPU) is an external power source that supplies electricity to an aircraft while it’s parked on the ground. Instead of relying on the aircraft’s onboard batteries or running its engines, a GPU delivers the exact voltage and frequency required to power avionics, lighting, environmental controls, and other systems. This makes it an essential piece of ground support equipment for maintenance teams, flight crews, and operators alike.
The benefits go beyond convenience. Using a GPU reduces strain on the aircraft’s own batteries, extending their life and cutting replacement costs. It also lowers fuel consumption and emissions, since there’s no need to keep the engines running just to generate power. Most importantly, a GPU ensures safe and reliable operations on the ground, whether you’re preparing for take-off, carrying out routine checks, or troubleshooting avionics. For any operator who values efficiency, safety, and cost savings, a GPU is a must-have.
The Different Types of Aircraft Ground Power Equipment
Start power units provide a quick, powerful burst of energy for safe and reliable engine starts. They protect aircraft batteries from stress and ensure engines turn over smoothly, even in challenging conditions.
Aircraft often require 400Hz power, which differs from standard mains electricity. Frequency converters transform power from the grid into the exact frequency needed for aircraft systems, allowing technicians to carry out maintenance safely and efficiently.
Battery carts give mobility and flexibility. They allow batteries to be charged, transported, and managed with ease. For busy airfields, this makes operations faster and safer, reducing downtime.
For extended maintenance or avionics work, continuous power units supply a stable energy source. This avoids draining the aircraft’s own batteries and ensures critical systems stay powered for as long as needed.
