I know this is taking us away from the current rhetoric but wouldn't two competent pilots encountering ordinary weather conditions at night with an autopilot disconnect because of IAS loss not be able to keep the ac straight and level for a few minutes? The captain, who seems the only competent instrument pilot, was required by regulations to take his rest. Normally flying the long hauls from south america it is divided evenly so all pilots get equal rest. We had the extra pilot figure out the times usually depending on who was flying the trip on when each took their breaks. Our airline had competent FO's in the other two seats so didn't worry about the difficulty of that leg.
I guess airlines hiring low time pilots out of pilot mills can't do that now.
