Sounds like the book is reffering more to a GPS than a VOR.
It's almost as if the author of this book knew what lay ahead
as far as computers and GPS with an MFD.

It seems to me that, at the time, for pilots who were used to flying MUCH
more primitively, with A-N radio courses, maybe NDBs, and no radar coverage
most of the time, the advances that brought VORs and near-100% radar
coverage were likely much like to them as GPS is to us.

In another 50 years, when we have navigation that positions airplanes to the
inch and tracks timing to the tenth of a second, we'll be reading
descriptions of GPS and thinking, "gee, it's almost as if the author knew
what lay ahead".
