Thanks, it’s not necessarily about aggressive decel, more the legality of flying the final descent into the approach as coded, which has the aircraft fly a level decel at an altitude above the ATC cleared altitude, which is also the commencement altitude of the approach. The proposed alternative is to either harden altitudes in the FMC to make the decel at 2500’, or fly a selected mode down to 2500’ prior to arming the approach. (A330 if it makes any difference)
Personally I can’t see a problem unless, as mentioned, you are given STANDARD RATE or some similar clearance, but I can’t find any reference to confirm either way.
