Hey,
most A330-300 do not have a center tank, which results in a fuel capacity of 97170 liters (78.125 kg calculated with a density of 0.804 kg/L at 15 °C).
The A330-200 is equipped with a center tank, which results in the fuel capacity of 139900 liters (112.480 kg calculated with a density of 0.804 kg/L at 15 °C).
Since the MSFS 2024 probably does not simulate different fuel densities, a fixed value was probably set at a certain density.
Is it the case in MSFS2024 that the A330-200 also does not reach the appropriate value? Unfortunately, I can't check it myself at the moment.
Kind regards,
