The A320 FCOM chapter 27 flight controls, normal law, protections, shows a diagram how the sidestick input is used when protections are active. When high angle of attack protection is active the side stick controls angle of attack (alpha protection to alpha max), so far so good.
In several places throughout the FCOM and that diagram I talked about Airbus states that the alpha protection has the highest priority.
Does this mean when alpha protection is active that pitch protection is no longer available? It makes sense that the nose of the aircraft is allowed to drop below the normally protected minimum of 15 degrees but is the maximum pitch of 30 degrees (or 25 depending on config and airspeed I think) still protected? When alpha prot is active is it possible to pitch up to more than the maximum pitch limit? The diagram would suggest yes.
