747 21.1 fuel issue

Does the 747 have the same fuel issue after in 21.1 where you had to load the fuel to full in order to have enough fuel to do long hauls ?

The 747 is still to be reworked with updated physics and performance - so yes the inaccurate performance is still there.

However I have found I only need around 3 hours extra fuel with the 747 when doing a LH - no where near full. You might be doing something wrong (e.g cruising too high for your weight, climbing too fast, cruising too fast, etc…)

Yea, make sure that you step climb, check winds. Full fuel is usually less efficient.
