ok guys the argument now is not between in flight and dispatch data.
just want to know the following:
FCOM Vol 1
Performace Dispatch
777-300 ER
Takeoff
Enroute
Landing (Landing Climb Limit Weight - 376.6)
Gear Down (Landing Climb Limit Weight - 335.7)
Gear down performance means gear cannot be retracted.
But landing climb limit weight is also calculated with gear down.
So what factor creates a difference in the limits.
Thanks both of you
