At what time do some airline pilots forget that, over anything else, they are, well, pilots?
And that "fly the plane" is always the first priority?
And that the Primary Flight Display has the words "Primary" and "Flight" on its name for a reason?
And that if you don't understand "what is it doing now", perhaps the best course of action is that YOU start doing something, like flying the damn plane yourself using, you know, the manual flight controls like those available in all planes from the Cessna 150 where you logged your first hour to this hi-tech Airbus where you logged your hour, how much? Oh yes, 23226 (3081 on type) for the capt and 9647 (2410 on type) for the FO????
Next time that something odd happens, would one of you keep the eyes on the PFD and take manual control if necessary while the other one plays with the ECAM, the AP, the AT, the FD, the radar and the radios?
