But this may or may not isolate the corrupt source. You’ve got a fair chance of turning off the two good ones.
Your real aim is to stop the aircraft reacting to any dud data, and to do that you want a law change. Turning off the PRIMS will drop it to direct law, but all of the ADRs will still be available for you to try to resolve which is the bad source.
My AB time is only on the 380, so I’m just extrapolating from it to the other types.
