2- A320 specific- When aligning the IRU’s, some people do 1-2-3, and others do 1-3-2. Is there any system-related reason that the order should matter? I remember this being discussed at one point, but I couldn’t find the thread.
Thanks for the replies.
The PFD and FCU values can be different in a case that is not exactly what you expect : when the pilot mistakes one knob for the other. Turn left heading 230 can soon turn into changing speed to 230kt. Checking on the PFD helps catching and avoiding this mistake.
The order does not matter but it helps pilots remember that 3 is in the middle, to do 1 2 3 instead of 1 3 2 which is more natural.

Everywhere I've been, people have taught me the "act and check" principle or whatever it's called in English.
