Quite interesting. I tryed it and for FMGS with MCDU menu I found it on:
MCDU menu
AIDS
Load Report
Requested a print and all values during landing event were printed.
Actually all values from 1 sec before landing to 2 sec after are printed. If you bounce, those values will be retained.
Some values are easy to understand what they are, as Pitch att, roll, etc., but there are some I have no idea. Those are:
LONA, LATA, PTCR, ROLR, RALR values
Can anyone decode those?
Cheers
