Fuel costs--jumps vs. weeks of operation

Postby Master_of_Ritual » Sat Aug 01, 2020 7:13 am

Under Fuel Tank for a ship the main book gives you a total amount of fuel, and a number of weeks of operation that that fuel provides. Is that the number of weeks of operation assuming you don't use the jump drive in that time, and then you recalculate accordingly when you jump?

That's weeks of operation for the power plant. Typically the fuel tank holds enough fuel for one jump + power plant fuel.

Calculate them separately then add together for the ship's total fuel capacity. In emergencies, you can use as much of that capacity for real space maneuver and power operations but at the expense of not having enough fuel for a jump. Once a jump happens, the rest is useable for lights. It's not two separate tank systems.

Default is pretty simple: ten percent per parsec to be jumped, the balance dependent on fuel consumption by the power plant, which views manoeuvre drive power requirements as overhead.

A ship that doesn't jump can run for a very long time on its fuel: even a basic far trader can go for 84 weeks before emptying its tank. This isn't a bug: a ship that isn't making regular jumps is probably going to be staying in system (in whatever capacity) for a long time.
