Boeing 777-200 Cruise Weight

[G-AMMY]

Assuming the aircraft departed at MTOW (approx 245,000kg) and half way into say a 10 hour flight, what would be the approximate weight of the aircraft?

I know that there are so many variables that effect this, but its only for a University project so a rough answer is fine.

Thanks in advance,

Per hour the B777-200 with GE engines burns about 7.000 KG, so half way you would have about -35 tonns. Equals 210.000 KG. The max landing weight is then 201.850 KG. Half way thru you need still to JETTISON some fuel when you want to land immidiatly.

Half way thru you need still to JETTISON some fuel when you want to land immidiatly. Why not land overweight?


For a MTOW of 245k, i preume that you are talking about the GE90-76 engine, we operate the -90 engine with a MTOW of 286k, I believe that the -92 engine has a MTOW of 295k.
