Referring to simbrief flight plan generation (using the Horizon simbrief profile), is anyone noticing that the fuel consumption is very accurate for the first 8-10 hours and after the consumption appears to be higher in the last hours for a very long haul flight?
Is the simbrief calculation or the simulator the problem?
I know that i can carry more fuel to be sure but I'm one who likes to push to the limit the plane, crossing the entire planet, so every kg counts 😄
