Pitch and power

Which computer? The AP and A/THR disconnected, and handed 'control' to the FCPC, which reconfigured to Alternate law. The purpose of 'pitch and power' is to "keep the plane flying", not to maintain altitude or airspeed (in UAS and in turbulence). The FCPC does just that - maintain pitch and power. Why can't it maintain bank angle?
