Finite State Machines and the need of "Graceful Degradation"

Hi,

I did study this issue and we could say the Systems placed in advanced planes like A330 are "somewhat" in this category.

These powerful mechanisms sometimes need a "Reset". There is the risk to enter some "States" and the Reset assures a "new begining".

My question is related to the need of "Graceful Degradation" on the planes, when submitted to anomalous "inputs" and requiring emergency manual "crew intervention"

Why A/P and A/THR are not "System designed" to "return" to the scene after an anomaly (like brief UAS) in this planes?
