Yeah, watch out for all the glitches, OEBs, specificities and such.
You can use managed-managed to perform an NDB approach (LNAV minima), if you like and you meet all those restrictions. But you have to x check with raw data. Similarly, you can shoot an RNAV to LNAV minima with FINAL APP (for instance if your company does not allow to shoot the same approach to LNAV/VNAV minima).
