If you have certain failures (or turn the computers off by pushing a button), you will experience a FBW downgrade, first to alternate mode, then possibly to direct mode, and the automatic flight and thrust will be unavailable for the rest of the flight.
I thought I did Aegean back at the beginning... Was it one of the A319 liveries?
Just a status update on the ECAM system: I'm working on the autopilot / autothrottle disconnection warnings. There's a few bugs need ironed out before it can be merged
The cockpit lighting is waiting for me to try and fix one last bug as well (I have no idea what is causing it...)
