If the flight plan fuel was calculated in error on a "light load" then:

a. If the ZFW increased dramatically preflight (and entered in FMC) wouldnt the FMC produce a scratchpad message to the effect "insufficient fuel"

b. If the ZFW error was not identified & the wrong ZFW entered into the FMC. Then wouldnt all the takeoff calculations of takeoff speeds & thrust be in error.

therefore

c. If reduced thrust takeoff used for the incorrect weight. Wouldnt the takeoff acceleration be unusually lower.

Perhaps someone with A320 experience could tell me, isnt the aircraft system designed to catch such errors? Is there a ECAM message something like "STAB BAND" which would appear if the FMC programmed weights differ to that in which the nose gear senses as actual aircraft weight?
