I have done a matlab code that plots the flight envelope from the three parameters. Its not very complicated if anyone wants to translate it to another language.
The negative g limit is dashed because the code doesn’t consider negative g forces so it doesn’t handle it that way. In fact it looks like it just imposes a hard limit of -1.1g. Although for inverted flight for example the limit is just tuned off. Also the stall prevention code would also alter the flight envelope if enabled.
The g limit code is here if anyone is interested.
