Nope, ZFW + block fuel is equal ramp weight, not takeoff weight. Takeoff weight is ramp weight - taxi fuel.
Your briefing will indicate “PAYLOAD/CARGO LIMITED BY MTOW”, although it’s not very intuitive since the passenger count is unaffected (IIRC real dispatch software does the same, except dispatchers are then smart enough to recompute the flight w/fewer passengers and/or adjust other parameters until this is no longer a factor).
@SimBrief in the new version, these weight limit remarks have been made less obvious, I would say? One could argue there’s no point in fixing it since apparently 90% of users have no clue what it means (and the rest who do can find them), but still, maybe something could be done to improve it a little? Perhaps they should be right below/above the loadsheet (currently separated by the flight route) and, when present, possibly highlighted in bold or something?
Also, recomputing passenger numbers is probably rather complex, but when payload is limited, just passing through the requested passenger count can be really pointless (easily half of the requested amount in some cases)? Even if somewhat unrealistic, perhaps the passenger count could be dashed instead to somehow convey that it’s not actually applicable anymore?
