Having completed a number of flights from and to airports with high(er) field elevation (e.g. SKBO, SEQM, KABQ, MMMX) it appears to me as if the cabin pressure control system does not take into account the landing field elevation (as set by the landing elevation selector) when regulating the cabin pressure. The A300/A310 FCOM states that "The cabin altitude is regulated towards the theoretical cabin pressure altitude determined by the controller, or to the landing field elevation, whichever is the higher." Flying into KABQ, for example, the cabin altitude descends to less than 4000ft on approach while the field elevation is 5350. According to the statement in the FCOM the cabin altitude should not descend below the field elevation. Although the controller at some time slowly climbs the cabin towards field elevation it never catches up and at the time of touchdown there is a residual 1000ft altitude difference (in case of KABQ) - the pressure difference even increases with higher landing field elevation. This leads to an unpleasant depressurisation for the virtual crew and pax when the controller completely opens both outflow valves after touchdown (FCOM: 45 sec after touchdown).

Any thoughts on this minor issue?

Thanks we'll look into it.
