Doves, what I mean is that the VORs andADF are not used to monitor the SID or STAR. The ILS and LCTR are typically tuned before top of descent, so if the FMC screws up, there is no way to spot it. I prefer having VOR/ADF raw data on the map mode needles all the way to the ILS.
It's normal in most operators for both pilots to have the ND on map, not APP or VOR (as appropriate) for the approach, though we are allowed to have the PF use those raw modes for practice raw data flying as long as the PM has the map on. That's a pretty reasonable compromise, as the PFD has small scale duplicates of the ILS anyway, and the map had the VOR/ADF needles.
