MAP vs Raw data

[shazapis]

Hello,

I need some help guys.

I am involved in developing standard op procedures for a newly upgraded military bird and I need some opinions on this:

The avionics suite has multiple position sensons (two INUs, two GPSs, blended INU/GPS solution etc and the EFIS has the capacity to build a very nice map display - pretty much like the one you get in the B734).

My question is: how do you fly a non precision approach from the standpoint of automation?

Do you build the prodedure up in the FMS prior to TOD and let the AP fly it in LNAV/VNAV?
After the FAF, do you need to have the PF in raw data (HSI mode and VOR/DME)?
Also, during transition to final (IAF-> FAF) do you have one of the pilots on raw data or is it all LNAV/VNAV?

BTW, the database only includes GNSS procedures (regular VOR/DME have to be built-up by the pilot). Also, the FMS does not talk to VOR/DME for the purpose of position sensing (it does interface with the receivers, but only for tuning them).

Please share your views on this with me.

Any reply will be very appreciated!

Thanks
