Power Plant fuel requirement question

[snrdg121408]

Evening all,

I'm a long time member of Traveller and I've picked up at least the main book for each version/variant. On 9/13/08 I picked up the latest offering from Mongoose and what I have looked at is very good. Unfortunately, I seem to have a slight puzzle in the Spacecraft Design chapter.

I'm using the Scout, Type S on page 115 to go through the design steps. From the ship data card the Scout has a fuel load-out of 40 tons.

Computing the Jump Drive fuel requirement I get 20 tons which leaves 20 tons of fuel for operating the power plant for 10 weeks.

Going to the Power Plant Tons of Fuel per 2 weeks at the bottom of page 107 a Power Plant A requires 2 tons of fuel per 2 weeks. I determined that 10 weeks of fuel, if I understand the text, requires
(10 weeks/2 weeks) x 2 tons of fuel = 5 x 2 = 10 tons of space for fuel. My calculations show that I'm 10 tons short from the data from the ship card.

Did I read the text wrong?

Nope it is an error.

It should be 40 weeks of endurance. OR, give the ship 10 more tons of cargo.

Crap, my mathfu is off, yes 20 weeks.

Hello Rikki Tikki Traveller and BenGunn,

Thank you both for confirming that I read the text correctly and that the formula I created in a spreadsheet actually came up with the right wrong number;-). Of course I used the spreadsheet after my paper, pencil, and calculator resulted in 10 tons vice 20 too.
