Landing Climb Limit Weight

Hi

Regarding B777 Landing Climb Limit Weight

A) Performance Dispatch => Gear Down => With Temp 30 C & Airport Pressure Altitude 0 => Landing climb limit weight is 335.7

B) Performance In flight => Advisory Information => With Temp 30 C & Airport Pressure Altitude 0 => Landing climb limit weight is 376.6

Both (A) and (B) are valid for approach with flaps 20 and landing with flaps 30.

According to the regulation the Landing climb gradient charts are calculated for go-around with the aircraft in the landing configuration where all engines are operating and the landing gear is extended.

Why is there a weight difference between (A) and (B). Is it something to do with the gear doors or it is something else?

Thanks
