Hello guys,

Did you notice that very recently on the landing computation on the Nav Blue Application for the A321 Neo now the landing CG is required? And it’s only for the A321 Neo...
The range is between 12% to 41% and playing with the number it only makes a difference just over 60 meters... A bit pedantic in my opinion.
Also recently with cargo flights we only have manual loadsheet so the landing CG is not available unless you do it yourself which we don’t normally. Edit: Looking at the manual loadsheet the range is only 16% to 34%. Of course we can always take the ZFW CG which is always more conservative or do the landing computation using the CG available in the performance page. It does not move much anyway during flight.
I’m just curious why they would add this input which is negligible and only for the the 321 Neo.

I believe it's got something to do with this (https://leehamnews.com/2019/07/19/bjorns-corner-airbus-a321neo-has-pitch-up-issue/).

Apologies for not having a more authoritative source.
