Hello Again. I have just been tinkering with various ZFW entries into the FMC and I can enter any value between 245Klbs and 179Klbs. My Question is... what if I want to enter a value of less than 179Klbs. What/Where do I have to make the changes. Changing the Aircraft.cfg file doesn't allow me to enter a lower figure.Thanks.

It is impossible to enter a value less than 179000lbs for one specific reason - this is well below the actual Empty Weight of a 763 without crew, catering pax baggage and fuel.

Yep... I know that. But just say...for the purpose of experiment... that you wanted the FMC to accept values less than 179Klbs... How would one go about that.. Thanks.

Hi,Ref questions on the FMC. Can anyone confirm the exact ref number of the FMC or relevant up date? On our 757 we cannot get the range ring on the fix page?Regards Simmslot ;(
