I have to agree with NIE above but add the following. Having been involved with Managed (Airbus) VOR/DME, NDB, GPS, RNP and RNP AR since inception, it is absolutely imperative that the coding of the FMS is checked intimately against the AIP of the country. In the early days there were massive errors in the coding resulting in the aircraft in auto flight descending abruptly, or not descending or levelling off during the approach. RNP AR has improved database coding , but there are still occasional errors. An airline is required to have a form of database checking, however it is certainly in the Airbus SOP that the PIlots are required to check the database coding against the chart before commencing the approach and ensuring it complies with the ATC Clearance and the charted approach. In my experience pilots often accept the FMS database as correct without checking. “After all the aircraft flew it OK last month”.
