My previous Asian employer still required an NDB approach. We used Map and LNAV for the PNF and raw data for the PF, using centre Map with the ADF needles wandering about ( as they do). The local regulator is smart enough to appreciate that this is different to a Baron with a fixed card and now your Instrument rating up there is 'Type Specific'. Makes sense to me.
In ten years they will be gone to where the VAR went.
