Aircraft Ground Power Units (GPU) for Starting & Maintenance

Ground Power Unit, or GPU for short, is the name given to power supply equipment that provides clean power for both maintenance and engine starting aircraft that are on the ground. A GPU, much unlike your average household power supply, is unique in that it provides a very specific “ripple free” or “clean” voltage, this ensures sensitive avionics and control systems within the Aircraft are protected during powered maintenance and engine starting operations.

START PAC® engineers have developed an extensive range of Aircraft Ground Power Units designed to meet all manner of end use scenarios, from providing reliable mobile ground power for remote airstrips through to powerful hybrid solutions for fully high throughput Aircraft Maintenance, Repair & Overhaul operations. All START PAC Ground Power Units are made in-house and combine quality components, unparalleled after sales support and a 1 year warranty as standard.


You need to ensure that you can start your engine at all times and you also need to perform software updates without compromising or even ruining your aircraft’s on-board batteries. This means that you require a combination GPU unit both for your remote operations and also, for smooth engine starting. Look no further: START PAC® has developed the SUPER PAC model line with both Lead Acid or Safe Lithium-Ion technology. You can now have the best of both worlds and enjoy peace of mind without compromise.

Perhaps your aircraft is voltage sensitive and equipped with an over voltage protection relay? Using a 28V jump starter would normally be a non-starter (excuse the pun). With this specifically in mind, START PAC® has developed a range of 26V starting solutions. The classic 24V and powerful 28V battery packs are still available, but the 26V enables every aircraft owner to have the security of owning a GPU that’s perfect for their aircraft.

Training, maintenance or software downloads require you to start your engine safely and power up numerous systems without running the engine; at the same time, however, you want to be comfortable in your cockpit and enjoy its air conditioning. And why not? The START PAC® product line can provide up to 400 Amps of continuous, clean, no duty cycle DC power, adapted for your aircraft and for as long as you need.

Maybe you don’t always have easy access to AC power because the fleet you operate is large and aircraft are not always parked close to the hangar? Considering this possibility, the START PAC® team has developed three, free-running combination GPU units. Two of them – Ranger and Hi-Brd 4 – are equipped with eco-friendly, diesel engines and permanent magnet generators in order to provide you with up to 150 Amps or 300 Amps of continuous power, respectively. The third option is the brand new START PAC GREEN, the world’s first emission free GPU; powered by a large 26V battery bank, it’s capable of starting any kind of electrically-started aircraft. Furthermore, its large battery capacity will provide enough 28V clean, continuous power to run aircraft systems, including air conditioning. Plus, you are still able to use it as a diesel unit in the hangar without causing pollution and emissions. Operating silently, its running entails spending half of the operating cost of a comparable diesel GPU.

Don’t let recharging issues get in the way of managing a complete fleet and performing multiple starts; let high battery capacity units designed by START PAC® do the hard work for you.

Each of these units – Ranger, Hi-Brd 4, START PAC GREEN – is more than capable of jump starting any type of aircraft engine.

START PAC® combination Ground Power Units will help you to preserve costly certified aircraft batteries and secure turbine engine cold starts at all times. The majority of our units (exceptions being the 3324, Ranger, Hi-Brd® 4 and START PAC GREEN) are equipped with our patented Quick Change design to ensure that batteries can be changed in less than one minute, thus saving you time and money on maintenance.

Please note that these units are NOT designed for battery charging.

All START PAC™ products come with a 1-year warranty on workmanship and materials.*
