Does starting the APU burn Fuel in Infinite Flight

I’ve noticed that the ground power under the ground options doesn’t actually supply power to the aircraft and I have to start the APU to get power to the aircraft when I spawn in. Does the APU burn fuel while on while sitting at the gate while I do flight prep and building my flight flight plan and what not?

Cool, I hope one day the GPU can supply power but was wondering if in Infinite Flight that running your APU will burn your fuel

I’ll direct you to the above.

So you’re saying that I need to add fuel from what SimBrief tells me my block fuel to run my APU in Infinite Flight for 45 minutes or so, maybe an hour while I do preflight or waiting for others in a flash flight? I know the APU will burn your onboard fuel, just wondering if Infinite Flight does it definitively since the GPU doesn’t work …

APU doesn’t take up much fuel to matter, I only ever add in 45 mins of extra fuel for diversions, go arounds or any other delays.

Mostly when you start your APU you will burn 1% fuel every 15 minutes. So it is not that bad.

It’s intentional the APU in IF doesn’t burn fuel. Even the GPU doesn’t supply any power.

They just need to add a cable so it gets connected 😅.

Not really, they need to add the power service too. Fingers crossed we see it in the future.

It should. However, according to my observation the fuel consumption display shows 0 I also tested with 0 fuel in the aeroplane and the APU worked so I assume it is not simulated like that in infinite flight.
Normally, when you turn on the batteries without any auxiliary power support, you should get a little bit of electricity in the aeroplanes but it is not simulated in this way either. They will add GPU connection in further updates.

I think that was a joke.

not true. if you turn APU on it burns a bit of fuel.

You can turn on the APU without having any fuel onboard so the APU does not need fuel and will therefore not burn fuel when the APU is on

@MathiasG APU in commercial airliners uses diesel fuel rather than Jet-Fuel.
There are electric-powered APUs as well but not commonly used in commercial airliners.

Are we talking about real life APU’s or the ones we have in IF? The ones in IF do not consume any fuel. I’ve tested them over more than an hour in several airframes and the amount of fuel did not decrease.

We talk about the ones in infinite flight, I just clarified @MathiasG 's statement about

APU doesn’t need fuel

isn’t true.

The APU does not burn fuel in Infinite Flight.
