vilas, … are these conditions mandatory or advisory …
This depends on whether the operator is operating under EASA or FAA approval.
EASA (or equivalent) is a requirement - prior approval - the operator shall provide evidence - CAT.POL.A.350
FAA is advisory - the Operational Landing Distance data used is advisory data based on the recommendations of AC 25-32 - The guidance in this AC is neither mandatory nor regulatory in nature and does not constitute a requirement. … to provide guidance to manufacturers for a standardized approach for computing time-of-arrival landing performance data - (which it appears not to do so for FAA operations).
I do not recall that Airbus publishes data for anything other than EASA FOLD performance. Thus FAA Airbus operators would be expected to use this, excepting dispensation (SAFO19001) where alternative, advisory data, would be based on AC 25-32.
