Would it make sense to have an easier way to revert to direct law without checklists/power off 2 out of 3 ADRU's. That way direct law can be entered in a safe and simple process more akin to AT and AP. The pilot then has a simplified baseline to return to in extremis when there is no time to decipher exactly which protections and control law they are in. Disabling 2 of 3 ADRUs creates a single point of failure in the last ADRU and is overkill when all that is desired is a direct law without protections. A second procedure could be followed once in direct law to stabilize a/c, configure to a safer place in the flight envelope and minimize the loads on the air frame e.g. reduce FL, set pitch and thrust. This would immediately remove overload from flight crew and put the a/c in the safest possible configuration.
Having to unstrap and leave the left seat is clearly a dangerous activity in an emergency.
