I am looking for any advice regarding altering the way craft spend fuel.
I know one trick already: craft consume 1 unit of conventional fuel per 10 minutes per 100 knots rounded down. This means that the Skyranger which has a top speed of 760 knots will spend 7 fuel per 10 minutes when in flight, and 3 per 10 minutes while patrolling. This gives the Skyranger a significantly greater range than a craft with the same amount of fuel but a speed of 600 knots, even though both would patrol for the same length of time. You can use this knowledge to set speeds strategically to increase or decrease a craft's fuel efficiency somewhat. This doesn't work for Elerium craft as they spend 1 fuel (1/5th Elerium-115) per 10 minutes regardless of speed, and patrolling will not reduce this.
I am looking for some other ways to alter fuel usage:
1.) increase or decrease a craft's patrol velocity or the percentage of max velocity at which it patrols
2.) increase or decrease the craft's fuel usage rate, especially for Elerium craft
3.) increase or decrease the amount of fuel a craft gets per unit of Elerium-115
4.) alter the rate at which a craft refuels
If you have solutions to any of these, or know anything else useful about craft fuel, please share!
