Quote Night Flight99: I think your logic is self defeating. In an airbus the standard procedure for taking control, and ensuring that you have control, is to press the red button and keep it pressed (whilst stating "I have control").
Thank you for your answer. I did not go to the end of my reasoning (such as it is) wishing to be short…my mistake. I did not criticize the A320 which I have flown a few years, nor the FBW system, but the side stick in that case…as opposed to a yoke as in the 777 for example. You are right in your description of the priority system but I hope you do not imagine that with a glider filling the windscreen, somebody will say I have control (the captain did not) and push the priority button etc…it is all reflex action. In that case the captain acted on the sidestick laterally and the pilot in the pitch axis (down). I just tried to say that the copilot seing the hands of the captain jumping on the controls will stop doing anything (that’s the best decision in such cases).
As for the original subject of the thread, I shall wait with you for more information, feeling very sad for the crew, and having a thought too for the mechanics who work very well in Perpignan, as elsewhere. I flew many test flights there after heavy overhauls, plus painting jobs, and I can tell you that static ports, pitot tubes, angle of attack vanes were checked on the ground by the mechanics then by the crew before the flight.
