I had thought pilots DID. Does Anyone know?


The Morse IDs on radionav beacons send so slow
that it's easy to write down "dots" and "dashes" and
use a laminated "cheat sheet" to decode the ID and
make sure it's the beacon you want.


As JJ mentioned, the morse code tone ID is printed in the block
for each VOR and VORTAC on sectionals and en-route charts.
Since before 1962 they've been printed as little bold-face dots
and dashes.

Probably the main reason those tone IDs are still there is that
THE FAA NEVER TOOK IT OUT OF REQUIREMENTS. The ID
keying is a terribly simple mechanism (so many still survive as
mechanical form) that it was simply kept. Much easier to keep it
than require each and every VOR and VORTAC to remove it.

The tone ID pattern, along with the tone itself, can be generated with
a single Microchip PIC or equivalent plus a handfull of passive
components...will last for years. :-)
