# What is the power generating capacity for an airport GPU?

What is the normal current for GPU power supply for commercial aircraft and how much power do they need while on ground (in kWh)?

I have read that aircraft need need 28V DC and 115V AC - what would be the percentage between both modes of supply?

Would it by possible to power GPUs entirely by solar power?

• You mentioned commercial aircraft but tagged this with general aviation. Are there specific aircraft types you are interested in? The power requirements will depend on aircraft size and type. Jun 14, 2016 at 16:15
• kWh is a measure of energy, not power. Energy is power applied over time. Jun 14, 2016 at 17:32
• @andrewmh20 Nope, you're backwards. See here for example. Jun 16, 2016 at 15:50
• @andrewmh20 Wh is watts multiplied by time. Power has the time component divided out. Jun 17, 2016 at 2:45
• @andrewmh20 I'm a software engineer at a company that produces watt-hour standards - I'm pretty sure I'm correct. Anyway, this is off-topic and we've discussed it enough. Believe what you will. Jun 17, 2016 at 2:47
