GPS and old-fashioned thinking?

The transmitter is such low power that it only transmits for a mile or
so. It doesn't overpower everything over a wide area.

So if you're travelling at 120 knots you get thirty seconds max between
the beginning of audibility and passing the obstacle. Depending on what
the radio is trying to tell you, and how long it takes to go through the
cycle, that may not really be much time.

The radio just says "Wires!" or whatever the obstacle is. Better than
nothing, no?

No. It has unintended effects (such as, on the ground it obliterates
all aviation communication for a few square miles, of interest to
aviators who live there). Many things can be justified under the "if it
only saves one life..." banner, but I'm not convinced that if I'm flying
in the scud, hearing "wires" in my radio while I'm trying to listen to
an ATIS is all that helpful.

"Wires??? Where? WHERE??? I CAN'T SEE ANY WIRES...O MY GOD I'M GONNA
DIE.... oh, six hundred feet below and half a mile to the right. Never
mind."

Now, was that three two zero at one five, or three one five at two zero...

SPROING... (as the other wires catch the wheels.

Did you even bother to look at the document I linked to?

No. I should have. But then, this is usenet.

I was assuming it was a continuous broadcast, involving little more than
a low power transmitter. According to the article..

An early focus on continuous, low-power radio warnings from hazard sites "turned out not to be a good idea,"

The system they are now considering involves...

low-power radar that would detect aircraft on a collision course with a hazard, then trigger high-intensity lights on the hazard and broadcast an aural VHF warning. That turned out better.

This addresses two of my concerns. Maybe I'm just too old fashioned.
It might actually be a good idea.
