When plugging an EIS of 2035 into FAST for the ERJ-175LR, the MTOW and block fuel increase from the baseline, which is not expected, as future EIS should increase technology levels and decrease mass. This occurs for any future EIS. An example is in the table below, when comparing Conventional, 2005 to Conventional, 2035.
