Disagreeing Flight Directors - A320
G'day All,
Just wonding if anybody would be able to shed some light.
On departure, GPS primary. No FM/GPS disagree. FMGC syncronised, Captain FD indicates a turn to intercept, FO FD is still squared for a few moments then begins to indicate the turn.
I have seen this usually during climb. One FD may indicated a different target attitude than the other.
Can anyone shed some light on what might cause this?
