It’s the continuity of knowledge that needs to be passed on.Some pilots employed by the airlines have never been to Cairns before they joined,so they have no knowledge of the terrain,let alone the 32 approach.Then you have the 35 CBR terrain.Remember the QF terrain incident a few years ago?The DME arrival into LST from SYD is another example.There would be other examples and they need to be part of a cyclical program,not practiced EVERY sim.There are too many “children of the magenta” out there.The FMC is only as good as it is fed and CHECKED.
