Dozy
Who knows what the ELAC will command if suddenly it finds its AoA to be well above alpha prot? The system is designed to avoid excursions into high AoAs, but if the AoA happens to be too high without he system being able to avoid it, because it is just a fake input, the system will not question how is that possible. It will just pitch down to regain alpha prot. But if the AoA remains fixed (because of the faulty probe) then it will keep pitching down, at eitherhigh or low mach number until it reaches alpha prot, which will not occur because it is corrupted. The ELAC is silly and will do its job as designed, believing it is in a stall.
In my opinion the system will command constant pitch down, and while in normal law, pilots cannot override it. I don't know, however, the intensity of that pitching down input.
