Hi Boslandew,
Some airways routes are still defined by VOR & DME, other RNAV routes (Lat & Long) don't need to have VOR defined radials.
Most of us now fly using RNAV. Any airways VOR is automatically tuned & can be displayed. We are still doing NDB / VOR approaches - so most of it would still be obvious to you.
Loran, Consul & Decca have gone.
