[Excessive Fuel use]

Ok, I am flying the A319 so the fuel calculations done by AS fuel planner are not accurate? I should use the figures from Simbrief, is that correct? Would doubling or even tripling the miles in the AS fuel planner provide me with enough fuel?

Let me get this straight: Use Simbrief's fuel calculations and skip the AS fuel planner.

However, checking Simbrief's OFP, there is an entry labeled G/C DIST and it has the same number as the AS fuel planner for the distance.

Finally, how much of an influence does the Cost Index have on fuel consumption? Does it really matter in the sim?

I have the same issue. I will post the AS fuel plan and the plan from Simbrief. I don't know what else I can do short of adding more miles to the planner. Should have been adequate but ran out of fuel and the aircraft shut down.
