That's what I found when I checked part 25 too. In AFMs I have reviewed, "minimum flight weight" is the term used to describe the design minimum weight referred to in part 25. No reference is made to any term known as "minimum zero fuel weight" here that I can find. Perhaps that term is a misnomer or even applicable to the regulations of some aviation authority other than the FAA? In any case, min ZFW is not noted as a limitation in the AFMs of the part 25 aircraft I am familiar with, nor can I find any reference to it in the FARs. "Minimum flight weight" is, and I thank you for your attempt to research the meaning of the term which is the subject of this thread. (min ZFW)
