Tom,this is one of those little quirks of PIC.Looking at your pic, you have not filled out the Perf Init Page, because when this is filled out GR WT is diplayed between the Runway length and the TOGW entry.I think the TOGW entry is used to enter the ramp gross weight minus taxi fuel.I have mucked about with the entry, and you are right in saying that if you use Kgs that the FMC converts it to lbs.I also noticed that this has no effect on the computed V speeds.Mark

Hi MarkYes, I just took the screenshot to illustrate what I was talking about. I've also noticed it has no effect on the computed V speeds,although I generally calculate V & VREF speeds manually.Thanks :-)

This is what the AOM says about it:"Takeoff Gross WeightEntry is included with the takeoff datalink request."So I guess this is the planned TOW.Martin767 fetishistIt's a lot like life and that's what's appealing

HiIf I enter the TOGW or rather what I expect to be the TOGW, the FMC seems to take my entry and convert it into lbs. Anyone know why this is? TIA
