[AIRBUS] FLS glide

Hi all,

recently flying an RNP approach where the FMGC glide was 3° after FDP, the charted glide was 3.04° (so within 0.1) and the FLS indication on PFD showing a glide of 2.9.
Technically speaking if we refer to the glide of the FMGC we are good to go (0.1 or less with the charted approach) but considering the FLS data we would end up beyond the limit (3.04 - 2.9 is 0.14 of difference).

Any inputs/ideas?

Many thanks!

No idea what the SOP for your airline is, but at my airline we check FMGS versus chart within 0.1 degrees. The PFD check doesn't give a tolerance figure in our SOP, and I understand it to be a 'reasonableness' check. If the FMGC/Chart check is within tolerances I would personally be happy to fly it.
