I don't have any information on FPA correction.But cold temperature correction to Final Descent altitude and minima is a must otherwise you'll bust it. FPA if not corrected it will be in error but to safer side and as you carryout Dist/Ht check you will have to keep correcting it. All I can say is with.FLS option installed it is corrected through FMS and is flown in FINAL APP. So Airbus may be leaving it to the operator's.
