You can explain how a VOR/DME works with a simple visual
model.

There is a large lake with an island in the middle. There
is a lighthouse with a rotating beacon that makes one
revolution a minute. It has a white beacon and a green
beacon, when the white beacon is passing North, a big strobe
light on top flashes and a very loud horn sounds.

You see the strobe light flash and 6 seconds later see the
green beacon sweep by. Where are you? 216 degrees from the
beacon. Ten seconds after the strobe, you hear the horn,
how far away? 2 miles.

So are both the white and green beacons rotating?

Don't you just need an omnidirectional strobe (with horn for
distance measurements) and a single rotating beacon?


VOR is the same, just faster.


Steer your boat so the bow always points to the light and
you've got an ADF homer.
