Negative CG?

[SoulFlight]

I noticed this now with several planes, for example the CLS MD-80 with the corresponding payload model from the downloads section. What does this
mean? I always thought this is a percentage from bow to tail, how can it be negative in the load info sheet?

the number FSp generates is given in % of MAC. not going to go into how its calculated.

its possibel the payload model wasent made correctly. or that might be normal for that aircraft. hopefull some one who knows a bit more
about it will answer. but for now, the only reason i can think is that there is to much weight Forword of the Datum
