A heavy 321 is 85t + but the same principle applies, know your aircraft and always GEC any figures a table or computer presents to you. The same PIC a few years ago was presented with a flight plan that had not included the payload so the fuel figure for a transcontinental flight was a a bit light. That was in the days of the manual take-off charts. The final load showed an increase in 16t to the TOW so they redid the V speeds. When they got airborne the aeroplane told them they had insufficient fuel to get to their destination. Realising why, the PIC did a tech stop to load more fuel on. A GEC would have saved a tea and bikkie session. In the Sydney event it would have saved his job.
Buttscratcher when the OM became the ultimate backup they thought they had simplified it enough that lack of use would avoid the incorrect figures being used. It was assumed that any crew would use the actual weight for the V speeds. The only reason to go up to the actual temp column was to check the RTOW figure for the W&B.
