Ground power unit (GPU) for the ATR 42 / ATR 72
Which portable GPU starts the ATR 42 and ATR 72, twin-engine regional turboprop airliners? Our recommendation, how to choose capacity, and a written quote within 24–48 h from Navirnet, exclusive distributor of Hawker Aero lithium GPUs.
Recommended GPU for the ATR 72: 28V
For the ATR 72 we recommend the GPU 28180 (180 Ah, 5,500 A peak), or two GPU 2880 in parallel.
It is a larger aircraft with a high starting demand, so we recommend the high-capacity 28V unit or two smaller units connected in parallel.
- Lithium iron phosphate (LFP): light, safe and long-lasting
- Supplied with charger and NATO aircraft cable
- Modular: two or more units in parallel for more power
Always check the starting requirements and ground power limits in your aircraft maintenance manual (AMM). We confirm the right model with every quote.
Three questions to pick the right unit
1 · Voltage: 26V or 28V
Most aircraft use a 28V system. Aircraft with low over-voltage protection (AW139, Sikorsky S-76D, Pilatus PC-6 / PC-12, Phenom, Eclipse) need a 26V unit.
2 · Capacity: 92 Ah or 180 Ah
The 92 Ah units (18–19 kg) are the easiest to carry. The 180 Ah units (34–35 kg, 5,500 A peak) give more starts per charge for larger aircraft.
3 · Parallel operation
All Hawker Aero units are modular: connect two or more in parallel to double or triple output and capacity, and still use each one on its own.

Frequently asked questions
Which GPU do I need for the ATR 72?
For the ATR 42 and ATR 72, we recommend the GPU 28180 (180 Ah, 5,500 A peak), or two GPU 2880 in parallel. It is a larger aircraft with a high starting demand, so we recommend the high-capacity 28V unit or two smaller units connected in parallel.
Can a lithium GPU start the ATR 72?
Yes. Hawker Aero lithium iron phosphate (LFP) GPUs are designed to start turbine turboprops like the ATR 72. They give a clean, stable start, reduce thermal stress on the engine and save APU or battery cycles.
How many starts do I get per charge?
It depends on the outside temperature, the starter and how the engine is started. The 180 Ah models give roughly twice the energy of the 92 Ah models, and two or more units can be connected in parallel when you need more.
