I removed all gas from my tanks how the plane still fly I never will know must be acts of god
Limited Fuel, fuel consumption, or any other way to say fuel use is not implemented into the sim yet, but it is a highly requested feature now that the Devs have confirmed Global Flight.
I can already see all the peanuts trying to fly with insufficient fuel and plummit from the sky and having no idea what happened.
We dont have emergencies at the moment so you will be able to fly with no gas at the moment. Feel free to make a feature request asking for this to be made impossible for the sake of realism if you feel the need to do so.
