Ah, I do indeed remember flying raw data VOR and NDB approaches. However, I recommend you look over the approach chart for the RNAV (RNP) Z Rwy 36 at Quito, Ecuador. I don't fly that these days, but I believe you will see more of the point; the only way this can be flown is with an FMC, and you really, really want to be sure the FMC knows where it is...
