    You must also adjust the third ECAM

    I believe you might be referring to the standby altimeter (the third BARO setting) rather than a third ECAM, since there are only two ECAM display units in the A320.

    As far as I know, in normal operations, the standby altimeter is not part of the ECAM’s logic for comparing BARO settings between the captain and first officer. In real aircraft, the "BARO REF 1/2 DISAGREE" message is triggered only when there’s a noticeable mismatch between the two main BARO selectors — not the standby one. But thanks for the input!

    Yes, sorry, I probably expressed myself incorrectly.
