Dozy, you are overthinking this.
I can assure you I am not. Part of the reason my old Prof was so leery of computer controlled and managed aircraft in the first place was the sheer amount of complexity required to cover, if not all eventualities, then at least a significant majority of them - and then regression-test the software and hardware to prove reliability to a level required by aviation regulations. Remember this was the '80s - when every line of code had to count, and the hardware specifications called for technology that was obsolete even by the standards of the time.
Dozy, we are not flying with the first design of Airbus 330 control laws nor even the second.
The software design is a work in process.
Airbus has an extensive protocol and infrastructure for maintaining flight control software. At this point, it is an engineering problem and capable of being handled without more than the usual superhuman effort.
Mad Scientist.
Doesn't C* use 'g' for control loop closure at high speeds and body angle at low speed?
