Also there are a few non-precision approaches that use the ils dme for step down fixes( Manchester springs to mind).Again what do you do if the dme does not display on the pfd.Do you store the dme as a new navaid and will it display it??
- NAV Selector to "VOR"
- Tune the respective ILS frequency in the VOR ctl pnl
- Read ILS DME on PFD
For Cat 3 you should do that only at start of final descent cause on the respective PFD you have no ILS indication
