How does fuel per km work?

[Quizzor]

I am guessing lower the number more fuel efficient the plane is?

Quizzor,

It's a measure of fuel economy.

Maybe I am not asking this correctly. Here is an example is a plane with 8lbs per km more fuel efficient than 15lbs per km?

Quizzor,

You must purchase the fuel that you use. Aircraft may burn different volumes of fuel based on drag, mass, engine efficiency and quality, etc. A plane burning 15 lbs/km will cost you 1.875x the fuel (which in turn costs money) than the plane using 8 lbs/km. Multiply the route length by fuel expenditure to estimate how much you have to spend in fuel per route.

Yes buddy, the lowest lbs/km are more efficient than the higher lbs/km ones.

you can help the furl efficiency by lowering the cost index and slowing the plane down some
