Once the fuel truck arrives and is connected there is that prompt to use the airplanes fuel system to refuel it.
Since I find it annoying (especially on a turnaround), I tried setting the delay to 500 seconds in the settings, but this setting is just ignored, it still asks to do it every ~30s.
How can I make the delay much longer since I don't need those reminders, they are so annoying. Saying once that the fueling is ready should be totally sufficient, I'd like to disable any repeated prompts.
