Correct, 30 flaps Vref is 118 kts at 180 tons...
Generally, BOW for our 747-200s is about 175 tons...
I doubt anyone flies with only a few drops in the tanks... so shall we make it 190...?
190 tons, my table, same as yours says 121... add 5 kts for Granny = 126 as Vth...
I am not with LH... cannot fly within 1 knot, sorry... too senile nowadays.
