B737 NG set up for ILS with non co-located DME
I'm curious as to how the nav systems can be set up in order to fly an ILS approach, where the DME is provided from a non co-located VOR?
Company SOPs mandate that both pilots hav the ILS tuned and identified for the approach, but I can't see a way of ensuring that the DME from the associated VIR station can also be monitored as there is no DME hold function.
The only solution I can currently think of, is for PM to have the VOR/DME tuned initially in order to cross check correct glide path indications crossing the FAP, and then tune the ILS.
All suggestions welcome from someone who is feeling a bit stupid.
