Hello,
I want to calculate the payload of an aircraft both in fsx and fs9 for a program i've been working on. I don't want to use the 1400 offset since it's not working with some aircraft like Flight's ATR and captain sim 707.
So what i do is read the ZFW and subtract the empty weight. So far so good, but although in FSX using FSUIPC4 it's possible to calculate an aircraft's empty weight using offset 1330, you can't do that in FS9 since offset 1330 is not supported in FSUIPC3 (tested it just for fun and it kept returning the same crazy value regardless the type of the aircraft).
So i was wondering if there's another way to read the Empty Weight using FSUIPC3.
