VOR and reverse sensing

Robert Perkins writes:

Regarding position, it's true that one VOR won't tell you your exact
position. But if you combine pilotage from a chart with the relative
position data ("southeast of the station", "west of the station",
whatever.), you will have your position.

You get an approximate position fix from a single VOR transmitter by
flying perpendicular to the radial and timing how long it takes you to
get to a different radial (say, 10 degrees off). It's not all that
practical or accurate in real-life, of course, but it does sort-of
work.

Apologies in advance if I've missed the point of the thread and
duplicated a previous posting.


All the best,
